Dry ice is solid carbon dioxide that stays at a freezing cold temperature of minus one hundred and nine degrees Fahrenheit. Unlike regular water ice, dry ice does not melt into a liquid when it warms up. Instead, it goes through a process called sublimation, turning directly from a solid block into a heavy gas.
When scientists place small pieces of dry ice inside a flexible rubber balloon and tie it shut, the solid ice immediately begins absorbing heat from the room. As the solid transforms into carbon dioxide gas, it expands to occupy more than eight hundred times its original volume. This rapid expansion traps the gas inside the rubber walls, stretching the balloon wider every second.
Because the gas cannot escape the sealed rubber, the internal pressure rises rapidly. Eventually, the mechanical stress exceeds the elastic limit of the latex material. The stretched rubber snaps open with a loud pop, releasing the cold trapped gas instantly into the surrounding air.
