This week's challenge is a super simple one. All you need is some skittles, water and a white plate or tray. Don't forget to share your skittle creations using #ScienceSparksChallenge
Place the skittles around the edge of the plate, carefully pour water over the top and watch the colours dissolve into the water.
Why does this happen?
Skittles are coated in food colouring and sugar. When you pour water over the skittles the coating dissolves spreading colour through the water.
Extension tasks
Can you think of other sweets that might work?
What do you think would happen if you used another liquid instead of water?
