WALKING WATER SCIENCE ACTIVITY

Aniwaniwa Fact #2

A aniwaniwa is light! Just like Ihu! Ihu is our light.

TOP TIP:

Try to use the same amount of food colouring in each cup.

WHAT YOU NEED:

Whitu small plastic cups or glasses

Paper towels

Food colouring in primary colours

Water

WHAT TO DO:

• Place whitu cups in a row and pour water in cups tahi, toru, rima and whitu. The fuller the cup is, the better.

• Add rima drops of whero food colouring to cup tahi and cup whitu.

• Add rima drops of kōwhai food colouring to cup toru.

• Add rima drops of kahurangi food colouring to cup rima.

• Take a half sheet of paper towel and fold it in half lengthwise and in half again lengthwise.

• Trim off some of the length so that there isn’t too much excess paper towel that will stick up in the air between each cup. This will make the water walk more quickly.

• Place one half of a rolled paper towel in cup tahi and place the other half in the cup next to it. Then another paper towel from cup rua and into cup toru. This continues until you have placed the last paper towel that drapes over from cup ono to cup whitu.

• Watch what starts happening. You should quickly be able to see the colored water begin to walk up the paper towel.
