Grow a Rainbow

A science experiment for even our smallest friends.

How to:

Fold a piece of paper towel into three

Use water based markers and draw on both ends of the paper. Mirror the colours on both ends.

Make sure you only colour a 1/4 of the way up the paper on both ends.

Fill two cups with water. Ensure the water is up high enough that the paper will be dipping into the water.

Place each coloured end into a cup.

Watch as the rainbow grows up and over the rest of the paper.
