This is somthing that this bee would never have to do
AND never wants to....
BUT ! Some ideas for sublimation in the ghetto:
1. a ceramic coated pan with a glass bowl on top: the glass bwl containing ICE !

2. a ghetto coldfinger made from a ' U shaped ' Florescant light bulb... Modified to have the electrical ends removed and flexible tubing attached....
Ice cold water to be pumper through the tube, with the tube stuck through a LARGE home made stopper to be fit into a HEAT resistant jar..
Sublime and scrape crystals from either the bowl bottom or the ghetto cold finger..
I'm sure there's more ideas out there
