Do you know how to make water walk? Practise your reading in English with this science experiment.
Do the preparation exercise first. Then read the text and do the other exercises.
Try this science experiment to make water 'walk'. You can even make rainbow colours!
Ask an adult if you can do the experiment.
This experiment works because of something called 'capillary action'. Usually water only flows down, because of gravity. But as the spaces between the fibres of the paper towel are so small, the water actually moves up, against gravity!
Trees also use capillary action. Water moves up the roots to feed the whole tree!
Did you see green water in the middle glass? That's because yellow and blue make green. You can do the experiment using different colours. Try using seven glasses to make a 'rainbow'!
