I kept seeing this Skittles experiment popping up on my Facebook feed. It was pretty simple, cheap, and quite entertaining.
We just arranged Skittles around the edge of a small white plate and then added some water, until it was touching all of the Skittles. Over a period of a few minutes, the colours of the Skittles slowly bled towards the centre of the plate.
If left long enough, the colours began to mix together. Most of our attempts ended with T1 or T2 shaking the plate and making the colours swirl together, or knocking the plate over completely. Luckily we had plenty of Skittles.
You can see from the pictures that the centre of our colour wheel wasn’t quite at the centre of the plate. I think this happened because we were using a plastic plate and it didn’t sit completely flat.
This was easily reproducible and the kids enjoyed doing it. They also ate the used Skittles once we were done!
