Hello all:

We've got one of those Supersaturated Environments cloud chambers on order
but wouldn't you know we have a request to use one today so we are going to
try a quick & dirty one. A how-to page on the web recommends "pure(not 70%)
isopropyl alcohol". To get this we'll have to get a gallon from our chem
stores.

What do others use? I'm hoping something else works also. Thanks for any
suggestions.
