- The raisins initially sink to the bottom of the 7up.
- Bubbles of carbon dioxide gas from the soda attach to the rough surface of the raisins.
- These bubbles act like tiny life jackets, increasing the buoyancy of the raisins.
- As enough bubbles accumulate, the raisins become less dense than the surrounding liquid and float to the top.
- When the raisins reach the surface, the bubbles pop or detach, causing the raisins to lose buoyancy.
- The raisins then sink back down to the bottom.
- This cycle of sinking and floating repeats, making the raisins appear to "dance."
Parent Tip: Review the logic above to help your child master the concept of dancing raisins worksheet.
