See title. My bong's bowl is broken, so basically i have a bong and downstem but no bowl. I'm really tempted to just fashion a quick fix one out of tin foil but I've heard mixed things about tin foil. If we use tin foil for cooking and such, shouldn't it be completely safe? Tin can't possible evaporate at the temperature of a Bic can it? I once looked up on Wikipedia that it was some ridiculously high temperature that definitely surpassed the combustion of butane. And I know for a fact that almost all hookahs use tin foil bowls, and plenty of people smoke those daily. So what's the deal? What's good blades? To tin foil or not to tin foil?
