r’. A cloud chamber is a simple particle detector which creates a cold atmosphere of super-saturated alcohol vapour. As a particle is emitted from the rod, it collides with the vapour, causing it to condence back into water droplets, forming these tiny white trails. To find out how to make a cloud chamber, check out the source video:

Alcohol rocket

Here you can see the ignition of ethanol vapour in a bottle. The wave of combustion travels up the length of the rocket, the rapidly expanding gas increases the pressure, and the resulting propulsion sends it flying! Find out how to make a rocket in this video:
