Marshmallows are full of tiny air bubbles trapped in a gelatin-sugar matrix. Lower the surrounding air pressure (like in a vacuum), and the air inside the marshmallow expands rapidly. When you let the air back in, the pressure crushes the now-weak walls. This is Boyle’s Law in action: volume of a gas increases as pressure decreases (at constant temperature).

Instant karma. Also, the teacher’s face. sience lessons lol

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 . Marshmallows are full of tiny air bubbles trapped

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. This is Boyle’s Law in action: volume of
