A siphon, also called a vacuum pot, has two glass chambers. Water in the lower chamber is heated until vapour pressure pushes it up into the upper chamber, where it mixes with the ground coffee. When the heat is removed, a vacuum pulls the brewed coffee down through a filter. It makes a clean, sweet cup, and the process is fun to watch.
