🌈 Serving Suggestion (for Fun!)
Okay, no one’s eating this one—but if you’re doing this at a party or classroom setting, pair it with:
- A mini science trivia game
- Printable volcano coloring pages
- “Lava Punch” (red fruit punch with floating gummy worms!)
🧪 Tips for the Best Eruption
- Don’t skimp on the dish soap—it gives the foam structure and longevity.
- Want a slower eruption? Pour the vinegar in gradually.
- Reuse the volcano! Just rinse, reload, and erupt again!
