This document summarizes an experiment where a soda can filled with boiling water is crushed when submerged in room temperature water. The experiment uses common household items like soda cans, tongs, and a juice container instead of lab equipment. When the heated can is placed in the cooler water, the pressure inside the can decreases faster than the pressure outside, causing the can to implode. This demonstrates how atmospheric pressure works. The document also compares this experiment to how popcorn kernels pop when heated, where the kernel expands outward instead of collapsing inward like the soda can.
