Skittles Science Fair DIY Science Experiment

If you have more candy than you know what to do with, try this experiment with your little ones. Sometimes playing with food is inevitable, but with sweet science comes knowledge!

⬇️ Steps:
1. Gather your materials – Skittles, plates, and a cup with hot water.
2. Arrange Skittles on a plate. Feel free to have fun with it and make more plates with different shapes.
3. Carefully pour the hot water on each plate until all the Skittles are touching the water.
4. Watch as the colorful rainbow effect starts to appear!

What's going on?
The colorful rainbow effect comes as the candy coating dissolves into the water. The coating is made up of sugar and food coloring. When the coating dissolves, the sugar and food coloring mix into the water to form a solution, or a chemical mixture, with the water.

Solutions like to be balanced. If there’s a lot of sugar and food coloring in one part of the water but not a lot in another, the solution will try to get balanced by gradually spreading out. That’s what you see happening as the rainbow starts to move away from the candy! Scientists call this process diffusion. 💡
