Never trust a marshmallow in a low-pressure environment. Also, clean-up is sticky. 2. The “Dry Ice in a Sealed Bottle” Facepalm What happened: A well-meaning (but soon-to-be-very-wet) student put dry ice into a plastic soda bottle and screwed the lid on tight. “For a cool fog effect,” they said. Three seconds later, the bottle launched like a rocket, leaving a crater in the classroom flowerpot.

When you drop Mentos into carbonated soda, the dissolved CO₂ rushes into those pits, rapidly forming huge bubbles all at once. The soda becomes a foam rocket.

Dry ice is solid carbon dioxide (CO₂). At room temperature, it sublimates — turns directly into gas. One gram of dry ice makes about 0.5 liters of CO₂ gas. In a sealed bottle, pressure skyrockets fast. Plastic bottles fail at around 3–5 atmospheres. Result: rapid unscheduled disassembly .

Let’s be real: science class isn’t always lab coats and Nobel prizes. Sometimes it’s a baking soda volcano that explodes onto the ceiling. Sometimes it’s the moment you realize you’ve been writing “sience” instead of “science” for three years. And sometimes, the best lessons come from a good old-fashioned .

Fun fact: Diet Coke works best because its sweeteners (aspartame) lower surface tension more than sugar, letting bubbles form even faster.

Instant karma. Also, the teacher’s face. The “Dry Ice in a Sealed Bottle” Facepalm

It looked like a sugary monster inflating and deflating.
