Vacuum Coffee Experiment #2 - Erlenmeyer Flask on Stove Top (part 2)
Channel: spamtrashed

Test #2, part 2. Still figuring out the measurements... and other things.
The coffee seems to boil inside of the Erlenmeyer when it returns to the flask. That can't be good...

Based on Jake von Slatt's blueprints in MAKE Magazine, but greatly simplified.
Setup uses an Erlenmeyer flask, glass tubing (bent with a cheap butane blowtorch), surgical tubing, and a beaker. 
The filter is a Thistle tube, with 4mm tube O.D., 1 1/2' funnel mouth and a Yama coffee filter around the edge. The Yama filter has drawstrings to close it around the mouth.
