Model Combustion Engine

Add a small amount of a combustible liquid, such as isopropanol, to the container and plug it. Then charge the two screws to create a spark between them. The spark will ignite the fumes within the container, causing a burst in pressure, which pops the cork off.

Comes in size small and not-so-small.
