I recently observed a liquid pooling at the bottom of my cloud chamber. It was purple in color and rather odd. It was certainly flammable, which leads me to believe that it was a result of solventing between the supersaturated alcohol and the canned air used for my chamber. http://imageshack.us/a/img525/7906/20121122131134.th.jpg [Broken] I'm not quite sure what it is. I know that it was probably a combination of the Isopropyl alcohol and the difluroethane, but I'm not sure on this. Could anyone help me out?
