Naomi got a "Rainbow Lab" kit at Christmas, which has a few experiments related to colour. There are a few crystals that soak up water and expand into a kind of jelly, then dry and shrink again. There are also some food colourings to try various combinations of mixes. She has had a lot of fun doing some basic science!

We got to do a proper design-of-experiments (Latin hypercube) to try mixing the colours in different combinations.

That promotion was easier than I expected!

The jelly version of the crystals

...and after they had dried out

This was showing how the colours ran into each other to make a rainbow effect
