(SHORTY: "Speaking of ghetto condensers....", Stimulants)
This works and is easy as hell to construct. A rubber stopper can be used to secure the condenser to flask and to insure no leaks.
It is a simple air condenser. I think was WizardX who said that it could be made more effective with the addition of some aluminum foil folded around it in a T shape. For the rxn's SHORTY normaly discusses (5-15gs E in a LWR) he says it works fine without the foil.
