Sensory Space: Liquid Patterns Created With Skittles
This activity could not be cheaper or easier but does create some lovely effects.
Simple pop a row of Skittles around the edge of a saucer.

Pour in the water and wait for the colours of the Skittles to bleed into the water creating interesting patterns.
All you need is a packets of Skittles, water and a saucer or bowl. Couldn’t be simpler.
