Sorry it is in Russian. At least I think it's Russian. Looks like a good survival tool.

That's pretty cool. How do you turn it off or stop it from burning -- just take the lid + coil off the jar?

I'll let you know after I build one and try it out. I would think you can cover the flame and it will extinguish, but it will still emit alcohol fumes.

Watching that video led me to a rabbit hole of other cool videos on how to do stuff, LOL. I stopped at drilling holes in glass.

I saw a bunch there too and will go back to check em out later.
