Dang that looks impressive. Something from my high school chemistry class looked just like it.
It makes really great coffee, but only two (American-sized) cups. It is one of the best conversation pieces in a house filled with unique finds. Nothing like a gas lamp and self-actuated balance that moves and gurgles coffee in a glass jar. My wife thought it was ridiculous, but after her first cup, she now asks me to use the little coffee maker. LOL
