Three seconds later, the bottle launched like a rocket, leaving a crater in the classroom flowerpot.
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 . sience lessons lol
