Rapmaster Reviewed by Rapmaster on . cooling methods I have a small glass chillum, and the problem is it's so short with no carb that the smoke is extremely harsh. At least, moreso than I'm used to. Any ideas on cooling methods? I figure sticking it in the freezer will work, but does anyone have any semi-permanent solutions or tips? Rating: 5
