Put a balloon on one end and wrap teflon tape on the other until it fits snuggly in the flask and your good to go.
Do you mean without stopper?
Another way if you have to go the non-glass route with the condensor is to use a suitable sized plastic softdrink bottle with suitably sized clear PVC tubing fed thru it.
String it up by the neck to the roof or something else.
You can cut a oval shaped hole in the curved neck to refill with ice and to one of the bottom feet you can use a tap for the outlet of melted ice. swis finds that bit tricky and uses any glues, silicones, he can get his hands on. It's leaked before now in to the oil bath. F--fSSSSSSSS
I just took a 48" flourescent light tube and knocked the ends off and washed with dishsoap and a clothes hanger with a sponge connected to it to remove the white inside.

A crude air condenser. :) If you wrap alfoil around it and shape four fins in a cross + shape you can get greater efficiency.
seems like that aluminum foil would be the coup de grace for the glass bomb that will shard thy arse if the pressure spikes
Just wondering if SHORTY has had any bad experiences with the flourotube?
I would think it is relativly safe, because SHORTY's ideas are usually well proven and effective. :)
I would think that the balloon would help alleviate some of the pressure. Doing a LWR swim doesn't see how there would be any great pressure spikes. Could someone explain?
