"My students were begging me to do 'just one more' experiment after this one. It's fast, it's safe, and it genuinely looks like magic — but they walk away actually understanding density and diffusion."

— Ms. Erika Johnson, 4th Grade Teacher

"It looked like real fireworks going off underwater! We tried it with different colors the next day just to see what would happen."

— Lucas R., 6th Grade Student
