Giant Bubbles

Make hu ge wate r bubbles at home ! You will need: • Dish washing liquid • Glycerine or corn syrup • Large bowl • Wire coat hanger • Ball of string • Electrical Tape • Jug

To make really good bubbles, for every 15 parts of water, mix in one part of dish washing liquid and a quarter part of glycerine. You can buy glycerine from chemists, but it is quite expensive. So if you plan to make lots of bubbles, corn syrup is a good, cheaper substitute. How to make your giant bubbles: 1. Mix the dish washing liquid and the glycerine in a jug. Stir it into a bowl of water. 2. Bend the coat hanger into a round shape. Bend in the hook so it is closed up and becomes the handle of your bubble wand. 3. Wind string tightly around the hook, and then coil it around the rest of the hanger. 4. Secure the string by wrapping electrical tape around the hook part. You now have a bubble wand! 5. Dip the bubble wand into the mixture. Make sure all of the string is covered with the mixture. 6. Remove the bubble wand and let some of the mixture drip off. 7. Make bubbles by moving the wand through the air. Stretchy water: Water Molecules hold themselves together by surface tension. Dish washing liquid weakens the surface tension, allowing water to be stretched into a thin film. A free floating bubble filled with air will always form a sphere. This is because the surface tension is pulling it back into shape, just like a rubber balloon. Source: Smart Kids Science by Priddy Books.
