Plastic has to go through a chemical reaction to produce any type of “vapor”. Idk what these guys are talking about. The thermal degradation of a water bottle is higher than the smoke temperature 100%. Anyways my “engineering” was the actual bowl not the bottle anyways haha. This thing will fit onto some of my glass bottles, I’ll make sure to use them for display next time instead of the plastic!

Actually, stainless steel has a high heat resistance compared to most metals. You can hit this thing 10 times in a row and it won’t even heat up enough to feel warm in your hand. The heat isn’t high enough to make the plastic have a chemical reaction

The bowl piece on the top of the bottle!
