Dry Ice - Exploding Bottles

Description

Professor Hal Sosabowski reveals the explosive power of subliming dry ice in this demonstration idea for Key Stage 3/4 chemistry lessons to show that gases take up much more space than solids.

As dry ice turns directly from a solid into a gas, its volume increases dramatically, creating enough pressure to explode a plastic bottle. The bottles can only take a certain amount of pressure, and the end result is an amazingly loud bang as the bottle explodes.

Professor Hal Sosabowski is a committed chemistry educator who shows how to safely recreate his inspirational demonstrations, which are both educational and spectacular.
