Dancing Raisins
This Demonstration is included in a bundle of 101 Science Demonstrations & Experiments. You can find this bundle here in my TpT Store. These exciting demonstrations use mostly inexpensive materials that you can find around your home or can be easily purchased. I show how to run the demonstration, give helpful advice and explain the science concepts behind it. Many of these demonstrations can be turned into STEM projects for your students.

Also please check out my bundle of 36 STEM Activities: STEM for the whole year!
Materials needed:
• Raisins
• 7-Up (or any kind of clear, carbonated beverage)
• Clear Glass / Beaker
Directions:
- Pour 7-Up into your glass.
- Put 8-10 raisins in the glass and…watch them “dance”.
The Science Behind this Experiment:
Raisins are more dense than water, so you would think, when put into a glass of 7-Up, they would sink…right? But inside of soda (or “pop” as we call it in Michigan), there is dissolved carbon dioxide gas. As this gas leaves solution, the bubbles cling to the raisins. Because the gas bubbles are less dense than the liquid, they float to the top, taking the raisins with them! When the bubbles pop at the surface, releasing the gas into the air, the raisins sink.
