Dancing Raisins Experiment
Make raisins “dance” with this simple science experiment! Drop raisins into clear soda and watch carbon dioxide bubbles lift them up and down while kids learn about buoyancy in a fun, hands on way.
Supplies Needed
- 2 Tall clear cups
- 1 bottle 7-Up
- Water
- Raisins
Instructions
- Pour clear soda into a tall glass about 3/4 full
- In your other glass pour water until 3/4 full
- Drop a handful of raisins into each glass
- Watch the raisins sink to the bottom of the glass
- Observe the glass with soda- tiny bubbles form on the rough surface of the raisins to make them rise to the surface of the water
- Watch the carbon dioxide bubbles pop at the top of the glass causing the raisins to sink again (this process repeats itself making the raisins look like they are dancing)
- Compare the water cup (where the raisins sit at the bottom and don’t float) to the cup with soda
Notes
- If the raisins don’t move your soda may be flat, use fresh carbonated beverages for best results
- Make sure your glass is clear so that your child can see the raisins dance
- Medium size raisins work better then really small ones
- You can use craisins for this experiment as well
