Siphon (Coffee Maker)

The original concept of a syphon coffee maker was invented by Loeff of Berlin in 1830, but the version we know and love today was created by . It’s also known as a “vacuum coffee maker”. It’s both a coffee maker and a science experiment in one.

Here’s how it works: There are two glass chambers. You fill the bottom one with water and put it on a heat source, causing some of it to turn into water vapor. This causes the pressure in the lower chamber to expand, forcing the remaining water up into the upper chamber, where it mixes with coffee grinds to brew. When the heat source is removed, the liquid coffee is magically pulled back into the lower chamber while the coffee grounds remain in the top. The result is a perfect cup of coffee with no gritty residue.
