Glass butane torch
This guy Steve bates,he has made himself a Butane torch only with glass and a small reserve of butane. I researched and I have found how the other butane torches look like, and this is really different, more safety and always in metal. But, his idea is ingenious, the glass is more ecological and not hard to recycle, but this is too risky ! If you drop this on the floor you'll be pretty sure you'll have a beautiful explosion !
