Since the Big Bang, close to 14 billion years ago, the universe has been expanding outwards. This means that galaxies are travelling farther apart and away from us, as the space in between them expands.

Each year, these wacky awards celebrate science’s silly side. While Nobel Prizes are awarded for groundbreaking discoveries, the Ig Nobel Prizes honour scientific achievements that first make you laugh and then make you think. Here are some of our favourites among this year’s winners…

The Mechanical Engineering Prize was awarded to a team of scientists who reanimated dead spiders for use as mechanical gripping tools. After noticing that dead spiders’ legs curl inwards, they realised that by applying pressure they could open and shut them, creating a mechanical claw that can pick up objects with irregular shapes.

SPECIAL DELIVERY!

Great news! Single-use plastic cutlery and plates, as well as polystyrene cups, have finally been banned in England, following similar laws in Scotland and Wales. Each year, more than a billion plastic plates and over four billion pieces of plastic cutlery are used once then thrown away. Lots of this plastic ends up in landfill and takes hundreds of years to decompose. But environmental campaigners say more need s to be done, as plastic bottles and other packaging – which are yet to be banned – make up most of the plastic pollution.

SMELL-O-VISION

Scientists are interested in Bennu because it’s a remnant from the formation of our solar system. It is older than planet Earth and is a lot like the asteroids that smashed together to create Earth and the other planets. By studying these rocks, scientists can journey back in time 4.5 billion years and start to unlock the secrets of the early solar system. In September 2023, as the spacecraft neared Earth, it released the sample, which fell through Earth’s atmosphere, landing in a desert in Utah, USA. The spacecraft then zoomed off to explore another asteroid. A quarter of this cosmic treasure trove will now be sent to scientists around the world to analyse. The rest is being saved for future generations of scientists to study. Maybe one day you’ll uncover the secrets of our planet’s past! © NASA Goddard’s Scientific Visualization Studio

Imagine watching a movie where you not only see and hear but also smell everything on the screen! Scientists in China have developed two wearable virtual reality (VR) devices that make this multisensory experience possible. One device attaches directly to the skin under the nose and the other is a soft mask. Both contain scented wax that can be heated to release the smell, like a scented candle. Between them, they can generate 30 different scents, from lemon and lavender to pancakes and pineapple. As well as making watching movies and playing video games a more immersive experience, this new technology could also be used in hospitals to help patients who struggle with memory loss.

In the latest asteroid adventure, NASA’s OSIRIS-REx spacecraft has delivered a precious package of space rocks to Earth. Seven years ago, OSIRIS-REx blasted off to explore a near-Earth asteroid called Bennu. When it reached Bennu in 2020, the spacecraft used a robotic arm to prod the asteroid’s surface, releasing a cloud of dust and pebbles which was collected in a container at the end of the arm.

12 awesome experiments to celebrate science! Try them for yourself or throw a science party to enjoy them with friends!

STATIC SLIME

Wow your guests with this crazy gloop that looks alive!

Yo u will need

A balloon Cornflour

Vegetable oil Food colouring (optional)

W hat yo u do

1. Blow up the balloon.

2. Measure 4 spoons of cornflour and two spoons of vegetable oil into a bowl with a few drops of food colouring. Mix together to make a gloopy slime. 3. Rub the balloon on your hair about 20 times to create static. 4. Put your finger into the slime and then hold the slime up to the balloon and see what happens!

CHROMATOGRAPHY DECORATIONS Decorate your room using science!

Yo u will need

hite paper towels W (kitchen roll) Water soluble felt-tip pens A 10p coin

glass with about half A a centimetre of water in the bottom String, at least a metre long

What you do 1. Cut out several 12-cm paper towel circles. 2. Fold each circle in half and then in half again. 3. Unfold each circle. Place a coin at the centre of a circle and draw around it using differently coloured felt-tip pens. Repeat with the other circles. 4. Place the tip of a cone into the glass of water, making sure the ink doesn’t touch the water, then watch and wait!

You should find

The slime will move towards the balloon! This is because it has a positive charge, while the charged balloon has a negative charge. The positive charge is attracted to the negative charge.

Tim loves the fact that everything on Earth is made of stardust, including us!

5. When the ink has almost reached the outer edge of each circle, take it out, open it and leave it to dry. Repeat with the rest of the circles. 6. Place two circles together and fold them in a rough concertina style, then tie the string tightly around the pointy end and open up the paper towels into a flower shape. 7. Repeat with the rest of the circles, spacing them out along the string. Now hang up your decoration!

You should find The water travels up through tiny gaps between the kitchen towel’s fibres. This is called capillary action. Inks are made up of many different coloured dyes. The water dissolves the ink and carries some dyes further than others, separating out the different colours. This is called paper chromatography.

P ART Y ! Create an edible solar system for your party guests to enjoy!

Yo u will need

Long lollipop sticks 350 g chocolate cake 100 g milk chocolate

200 g white chocolate 1 tsp vegetable oil Food colourings

W hat yo u do

1. In a large bowl, crumble the cake with your hands.

Makes 8-10 cake pops

2. Ask an adult to melt the milk chocolate for you and mix it into the cake crumbs. 3. Use your hands to shape the mixture into balls and place them on a tray in the freezer for 15 minutes to firm up. 4. Ask an adult to melt the white chocolate and dip the end of each lolly stick in the melted chocolate before pushing it into a cake ball. Put in the fridge for another few minutes. Keep the rest of the melted chocolate warm. 5. Mix the vegetable oil into the remaining melted chocolate, add a few drops of food colour and partially mix to make marbled patterns. 6. Dip the cake balls into the coloured chocolate and twist to coat them, then leave to cool.

WHIZZ POP BANG? Can you pierce a balloon without popping it? Try it and see!

Yo u will need

1 balloon Cooking oil Wooden kebab skewer

What you do 1. Blow up the balloon and tie a knot. 2. Dip the tip of your kebab skewer into the cooking oil. Holding the balloon by the knot, carefully pierce the balloon about 2 cm from the knot using the pointy (and oily) end of your kebab skewer and twisting as you go. 3. See if you can poke the skewer right through the inside of the balloon and out the very end of the balloon (remember to twist the skewer as you pierce the balloon).

Yo u sho uld f ind

The balloon is more stretchy at each of its ends. If you were to poke the skewer through the balloon’s sides, it would pop because the rubber there is already stretched to its limit. However, the looser rubber at the ends can stretch around the oily tip of the skewer, allowing the balloon to stay inflated.

MAGIC ICING

Amaze your party guests with icing that morphs from purple to pink and blue!

You will need

50 g icing sugar 1 3 red cabbage leaves (or use 20 blueberries for less vibrant colours)

12 biscuits or cupcakes Lemon juice Bicarbonate of soda A small, clean paintbrush

What you do

1. Ask an adult to help you cut the cabbage leaves into small pieces then put the pieces into a bowl with 3-5 tablespoons of water. If you’re using blueberries, put these into the bowl without chopping them, with only a sprinkling of water. 2. Ask an adult to whizz the mixture with a hand blender until finely chopped. 3. Strain the liquid into a cup or glass using a fine sieve or a clean piece of fabric. 4. Add 3 teaspoons of the strained liquid and 5 teaspoons of water to the icing sugar and mix. It should be smooth and glossy – add more liquid or icing sugar if it’s too thick or runny. 5. Separate the icing into three bowls. Mix a small pinch of bicarbonate of soda into one portion and a few drops of lemon juice (plus a bit more icing sugar) into another. Watch as the icing changes colour! 6. Spread the three different colours of icing onto your biscuits or cupcakes. 7. In a cup, mix half a teaspoon of bicarbonate of soda with 1 tablespoon of water. Squeeze some lemon juice into a separate cup. Once the icing has set, use the paintbrush to paint some designs onto your icing using these two liquids.

You should find

Cabbage and blueberries have pigments in their skin that are a natural purple colour. These are indicators. When they are mixed with acids, like lemon juice, they turn pink. When mixed with bases (alkalis), like bicarbonate of soda, they turn blue. Use the icing to experiment with other ingredients. Can you tell if they are acids or bases?

VANISHING WATER

Did you know that bamboo grows faster than any other plant on the planet? Some species can grow up to 1 metre in 24 hours! This makes it super useful for growing building materials quickly.

BED OF PINS

1. Before you perform your trick, tear open the nappy over a large bowl and shake out the small amount of white powder. Remove any big fluffy bits of cotton wool and put the white powder into one of the cups. You should have about a tablespoon full. Will a load of pins pop a balloon? Your

party guests will be amazed by the answer…

2. With your audience sitting in front of you (so that they can’t see into the cups), arrange the three cups in a row. Pour about eight tablespoons of water into the glass. Have a sip to show that it’s normal water, Blow up two balloons and tie the ends. Put a drawing pin on then pour it into the cup containing the powder. a surface, pointy side up, and press the balloon onto it. What happens? Now place about 15 pins on the surface, pointy side up, 3. Swap the cups around a few times, then ask close enough together that they are touching. Press the second the audience to guess which one has the balloon down onto the pins. Be careful not to press too hard – if water in. the balloon pops, you don’t want your hand to hit the drawing pins! 4. Turn that cup upside down (making sure they can’t see inside it!) to show that it appears empty. Then turn the other two upside down When you press the first balloon onto a single drawing pin, as well. Where’s the water gone? all of the pressure is concentrated on one point so the balloon easily pops. When you press the balloon on the bed of pins, the pressure is spread across the surface of the balloon reducing the impact of the pins Your audience will be amazed to see that the water has so the balloon doesn’t pop. This is how disappeared! This is because the white powder is sodium magicians are able to lie on a bed polyacrylate, a polymer (a long chain-like molecule) of nails without getting hurt. that can absorb 300 times its own weight in water (which is why it’s used in nappies!). The polymer and water form a solid gel, which sticks to the bottom of the cup when it’s turned upside down.

AL ANIM S TIC

Gorillas This month our vet Joe Inglis is heading to the tropical forests of Africa to party with the largest primates on the planet.

Gorillas are great apes, closely related to chimpanzees, bonobos and those other famous apes, humans (they share around 98% of their DNA with us). Their home is Africa, where they live in lots of different environments, from mountain cloud forests to lowland swamps and marshes.

267 kg The weight of the largest gorilla ever recorded, that’s three times heavier than a typical man! Most male gorillas weigh around 170 kg (or the same as two large men) and females tend to be smaller and lighter.

Gorilla grub Despite their size – and fearsome-looking sharp teeth – gorillas are mainly vegetarian, eating leaves, plant stems and fruit. They occasionally snack on insects, such as ants and termites, and snails. They can munch their way through up to 30 kg of food every day!

A-grade apes A gorilla can bite harder than a lion. Answer on page 34

Gorillas are highly intelligent and, like other great apes, have rich emotional lives, showing feelings of happiness, humour, sadness and grief. Gorillas have been seen using tools like sticks to measure the depth of swamps before they cross and using rocks to smash open palm nuts. One famous captive-born gorilla called Koko was taught sign language. By the time she was 40 years old, she was thought to understand around 2,000 words of English and use sign language to communicate with her keepers.

Trooping the colour

Why do gorillas have big nostrils? Because they have really big fingers!

Gorillas under threat

Powerful primates Although generally placid and peaceful, gorillas are amazingly strong and powerful. They use their super-strong muscles to pull down banana trees and break branches to form nests to sleep in at night. They have also been known to use their strength to bend iron bars to escape from captivity!

Even after the remarkable physical changes through metamorphosis, butterflies and moths can remember experiences Chris Packham Wildlife presenter they had while they and conservationist were caterpillars!

Sadly, all gorilla species are under threat in the wild, thanks to loss of habitat, hunting and human diseases like the Ebola virus which can also affect them. However, there are lots of conservation efforts under way, including the Great Apes Survival Project and the Gorilla Agreement, which are helping to protect the remaining populations of these super-special relatives of ours.

A group of gorillas is called a troop and it’s led by a dominant male called a silverback (because of the silver hair on the back of mature males). It includes females and their offspring and sometimes other younger adult males called blackbacks. The biggest gorilla troops can include 30 individuals.

Turn the joggers inside out and draw lines as shown using a felt-tip pen. Carefully cut along the lines using fabric scissors. Cut off the cuff at the bottom of one leg, and cut around the top of the same leg, cutting two long tabs, one either side of the seam, as shown.

Draw a line 4 cm below the wide end of the tail. Cut a series of notches down to the line.

3 Gather the narrow end of your tail together and fasten it tightly with a rubber band. Turn the tail the right way in, then stuff it with filling up to the line you drew in step 2.

Gakk’s arms and legs move up and down as you pull the string. They are hinged at the same point on the body as real arms and legs to make the movement look realistic. The joints at our shoulders and hips are called ball and socket joints. They allow us to move our limbs in lots of ways – backward, forward, sideways and rotating movements, perfect for throwing your best dance moves! Puppetry has been around for thousands of years. Puppets range from very simple ones, like finger puppets and sock puppets, to complicated puppets containing levers, gears or compressed air that might be operated by two or more puppeteers.

Riddles Check your answers on page 34.

As well as keeping you fit, dancing also exercises your brain! Scientists have found that music and dance activate lots of different areas of the brain, especially those involved in vision and hearing, movement, decision-making, coordination and learning.

2. Evren was born in December, but his birthday is always in the summer. How is this possible? 3. Iona was 7 the day before yesterday, and next year she’ll turn 10. When can this be possible? When we hear music, we can’t help wanting to dance! Brain scans have shown that even when we listen to music but stay perfectly still, the motor (movement) areas of our brain still light up.

Dancing increases levels of a brain chemical called serotonin, which makes you feel good!

What yo u do 1. Cut out the templates over the page. If you like, you could stick them onto cardboard first to make them stronger. 2. Using the skewer, make holes through the four black dots on the body section and the one on Gakk’s hat. 3. Thread a piece of string through the hat and make a loop, then tie a knot to hold it in place. 4. Take an arm and make holes through the two black dots, being careful to keep the hole at the very top of the arm smaller. Repeat with the other arm and the legs. 5. Push paper fasteners through the holes in the body section and then through the larger holes in the arms and legs to attach them together. Make sure they can move easily. 6. With Gakk’s arms pointing down by his sides, thread the string through one of the small holes. Tie a knot in the end, making sure it is big enough so that it can’t go back through the hole. Now thread the other end of the string through the hole in the other arm and tie another knot as close to the paper as you can.

7. Repeat step 6 with Gakk’s legs. 8. Tie another piece of string around the middle of the string that connects the arms. Run it straight down Gakk’s back and then tie it around the string that connects the legs. Leave the string long enough so that it dangles down about 12 cm below Gakk’s feet. Add a bead to the end of the string if you like. 9. Now hold Gakk up by the loop at the top and pull down on the string to make him dance!

Interview with a SCIENCE HERO

In my job I get to... use science to bake!

“

My mum wasn’t keen on me helping in the kitchen because I was very messy!

Ravneet Gill, TV presenter an baker, d psychologist

“

Rav presents several programmes about baking and is a judge on Junior Bake Off.

”

She is such a good cook, but when I was young, the kitchen was her territory. I could watch, but I didn’t help. In my teenage years, I started helping my mum a bit more. I made samosas (pastries with savoury fillings) and rolled our rotis (flatbreads). I used to make pancakes with my dad too – I loved those!

I have always LOVED science!

”

At school, I especially enjoyed biology and chemistry. I’m a huge animal lover, so any lesson that was based around biology or animals made me really happy and engaged. I studied psychology at university and the whole time I was studying, I cooked and baked for everyone. In the back of my head I knew I’d love to be a chef, so after I’d finished my degree, I started training and working in kitchens. It wasn’t always easy but I learned so much.

“

I use science to help me every day.

”

I love working with recipes that involve sugar temperatures! After years and years of monitoring what happens when you heat sugar to various temperatures, you get used to what the pan sounds like, what the bubbles might look like, what the smells are. There are so many different signs to look out for and I think it’s fun to know how sugar changes at various temperatures.

Interview with a SCIENCE HERO

“

The highlight of my career was getting the job as a presenter on Junior Bake Off.

”

Never in a million years did I think that would happen. We laugh a lot, usually with the bakers when they are dancing and having fun. Liam’s dancing makes everyone laugh too, and he’s always messing about in the golf buggies. It’s a lot of fun.

Rav is a huge animal fan – this is her cat Armand

“

On the Junior Bake Off set

Cooking involves lots of experimenting.

”

It took me countless hours to nail making a Portuguese custard tart in a home oven! I had to make so many over and over again to get them right. Sometimes they would explode, or the custard would scramble, burn or spill over the cases! I think it took around 20 attempts, but I got it right in the end.

HOW STUFF

WORKS 1

The most important element of a laser tag set-up is the laser tag gun, which is usually made of plastic and designed to look like a futuristic sci-fi weapon. They are often called phasers or blasters.

Laser Tag

Laser tag has become one of the most popular party activities around the world, allowing people to battle each other safely using light beams and smart vests. Here’s how the technology works…

Despite the name, most laser tag guns don’t actually fire lasers. Those super-intense light beams can be dangerous. Instead, they emit a highly concentrated beam of infrared light, which is light with a longer wavelength than the visible colours we can see.

The infrared light beam is emitted by an LED light source, similar to those used in TV remote controls.

As well as registering hits on an opponent, the infrared light from each gun is also encoded

with information

about the user firing it so it’s possible to tell exactly who fired each shot in the game.

24 whizzpopbang.com

The beam of light from the LED is focussed through lenses to form a very narrow beam which shoots out from the end of the gun barrel. The best blasters can fire beams up to 200 metres and work outdoors as well as inside darkened arenas.

7 Because infrared light is invisible to us, some laser tag guns also shine some visible light as well, to allow the players to see the beams shooting through the air.

In indoor laser tag arenas, dry ice fog is sometimes used to show up the beams of light.

As well as carrying laser tag guns, the players also wear vests or headbands which have infrared sensors on them.

When a beam of infrared light hits one of the sensors on the vest or headband, it creates an electronic signal which is decoded by a microprocessor. The information about the shot and shooter is then sent to the central game computer.

Laser tag vests also have special features to indicate when a direct hit has been registered, including

lights, sound and vibrating motors which make the vest buzz.

The longest laser tag session ever recorded went on for 26 hours!

At the end of the game, all the information about who shot whom is analysed and displayed on a screen, with the players ranked according to how many players they shot and how many times they were hit themselves.

On the second line, we know the pink drink contains 100 ml so the green drinks must contain 60 ml each (120 ml total). On the third line, we know the green drink contains 60 ml so the orange drink must contain 120 ml. Now we can see that the bottom row must be:

They are known as flying frogs or parachute frogs because they can leap from branches and glide over 15 metres, using their webbed feet and loose skin flaps on their sides to catch the air. They also have large toe pads to help them land softly and stick to tree trunks.
