Then I show you how to actually make cold fire by removing the thermal energy of the gas ions while still keeping the thermal energy of the free electrons! This is an amazing cold fire that you touch and not get burned!Watch the video from The Action Lab for more info:

The quartz tube acts as a dielectric that keeps electrons from escaping and allows argon to be ionized and wafted gently from the tube before it can reach thermal equilibrium.

The result is a faint blue glowing flame that’s barely above room temperature but still has all the reactive properties of a plasma. The video shows all the details of construction and shows the torch in action.
