How does an ethyl alcohol hand boiler work?

I have been given an ethyl alcohol hand boiler and have no idea how it works.

Well, it just works by adjusting the heat temperatures. The heat of the hand changes the pressure that is going to affect the alcohol. For more information on its use, I strongly recommend going on the web for step by step directions as this will help you figure it out with no problems.

Hold the boiler in your hand. The heat transfer from your hand will vaporize the ethyl alcohol in the glass. It will rise up the tube to the top and 'boil'.

The heat of your hand changes the pressure in the glass ,so forth making the Ethyl Alcohol go up the tube,and it boils just a little bit above room temperature.

The heat of your hand on it changes the pressure in the glass chamber which pushes the liquid up. but i am not sure what else...

The alcohol boils at a temperature slightly more than room temperature. When you grab it, your hand warms the alcohol to over boiling point.

The ethyl alcohol does not boil; it vaporizes. The heat from your hand causes a pressure change in the gas inside the" boiler" and vaporization of the ethyl alcohol..  add a comment

It is primarily the expansion of gas in the bulb that pushes the liquid upwards. The liquid is very volatile which adds to the gas pressure - but it does not actually boil.
