I have the idea to use the thick mouthpiece of a glass coca cola bottle as a bowl, breaking the bottle up to where i only have this mouthpiece then putting a screen in it and using this bowl for a steamroller. Would this work out good?
Depends on what kind of glass it is. If you heat up some glass to a certain point, it could shatter or violently explode.
Hmmm, let's study this idea in a mathematical fashion. Stoner + weed + broken glass - (common sense) = Trip to the ER
You're kidding ME? right? Unbalanced heating can exceed the limit for internal thermal stress and as a result, glass can almost literally explode. It will shatter violently in some cases. Just because it's glass does not mean it's smokeable. I don't even know how a Coke bottle is being compared to a bowl.
He said he was just going to break it. And besides, it's not like hes going to put it in an oven or a microwave. If he was going to use heat you would dip a string in alcohol, tie it around the bottle, light it, then dip it in water and sand the break.
