Who knew the magic of a strong paper towel (other than every parent on the planet!)? Amaze the child by using one to make water walk from one cup to another, and teach them about absorption, saturation and gravity at the same time!
You will need
- at least 3 empty glasses
- water
- food coloring
- paper towels
- Fill a jar for each colour and add food colouring. You will also need an empty glass for each colour.
- Cut a paper towel in half and then fold it into quarters lengthwise. Stick one end of the paper towel into the coloured water and one end into the empty jar.
Thanks to capillary action the water moves or “walks” up the paper towels into the empty jar. The middle jar fills up with water until the water levels of all the jars are equal.
