Don't play with these things underwater. The molten metal stays in bubbles,
which sink onto you, burning nice holes in skin or suit.

The O2 and Hydrogen bubbles often explode, and you need a helmet to use it.

If a larger pocket of gas forms, (bigger than small bubbles) the resulting
explosion will be big enough to maim or kill. (It often does).
