Prof Hal Sosabowski reveals the explosive power of subliming dry ice, in this demonstration to show that gases take up much more space than solids. As dry ice turns directly from a solid into a gas, its volume tries to increase dramatically creating enough pressure to explode a plastic bottle. Those bottles can take a lot of pressure, and the result is an amazingly loud bang. Prof Hal Sosabowski is a committed chemistry educator, evangelist and communicator. Hal shows us how to safely recreate his inspirational demonstrations, which are both educational and spectacular.
