Rainbow Skittles science experiment. Skittles go around the outside of a plate and water causes the colors to come off the Skittles and move toward the center of the plate.

Setting Up the Skittles Science Experiment

Supplies Needed:

  • Plate
  • Warm water
  • Skittles (Try different colors and flavors!)


  1. Grab your plate and organize the Skittles in a circle around the edge of the plate. Kids can try different color patterns each time they do the experiment!
  2. Gently pour water in the center of the plate. Warm water works better than cold. Make sure there is enough water to go past the Skittles while filling the plate.
  3. Wait and watch the Skittles colors move towards the center of the plate with beautiful rainbow streaks.
  4. That’s it. It’s so quick and easy!
Use Skittles to teach science and wow the kids in your life.
This Skittles science experiment is so colorful and engaging!
Colorful rainbow science that kids of all ages can do!

The Science Behind this Rainbow Science Experiment:

Skittles are coated with sugar and food coloring. When you add warm water to the Skittles, the sugar and food coloring start to dissolve. They have similar amounts coated on them so they dissolve at similar speeds and stay in their lanes.

The sugar is moving to areas of water with lower sugar concentration. If the water is poured in the center, this is happening for each Skittle at relatively the same speed.

I hope your kids have a great time with this fun Skittles rainbow experiment!
