Be careful while working with glass! You can easily cut yourself!
In this video I show you how to make amazing coffee machine from 2 light bulbs. All needed components are shown in the video.
A vacuum coffee maker operates as a siphon, where heating and cooling the lower light bulb changes the vapor pressure of water inside it. Water is pushed up (or pushed down) the siphon tube into (out of) the upper light bulb. Just 5 minutes and you will get fresh coffee :)
