Dancing Raisins Motion Science Experiment
In this fun and easy motion science experiment we are going to show you how to make raisins dance. This experiment will use a clear carbonated beverage to make raisins float and sink in a way that seems to cause them to dance. This is a fun visual experiment that we will show you how to not only perform, but how to also change into a science project.
- Clear carbonated soda like Sprite or 7-Up
- 2 Clear Cups
- Pour the water in one of the clear cups. This will be your scientific control cup.
- Add the clear soda to the other cup.
- Now put some raisins in each cup and observe.
WATCH THE QUICK VIDEO TUTORIAL!
How it Works:
The tiny bubbles in the carbonated soda attached to the wrinkles on the raisins. The bubbles cause the raisins to float toward the surface. Once the raisins reach the surface, the bubbles pop and the raisins sink back toward the bottom of the cup. The raisins begin picking up more bubbles, float toward the surface, pop and sink again creating the dancing effect.
Make This A Science Project:
Try and test different items other than raisins to see if you can get them to dance. Try different types of carbonated beverages. Try tall containers to see how high the bubbles will lift the raisins.
