How Does the Popcorn Dance? (Science Secret!)
When vinegar mixes with baking soda, they make tiny gas bubbles! The bubbles stick to the kernels like little life jackets and lift them to the top. When the bubbles pop, the kernels sink back down!

My Conclusion
The corn kernels danced because the bubbles / heavy rocks lifted them up!
