A guy over in the modders forum builds lots of stuff. One of them was a hand warmer that he converted into an e cig. It's a metal tube that had a core you would heat and it would keep warm all day. He put a pan inside that you dripped onto
through a hole and it would vaporize the
juice which you could inhale. Keeps your hands warm too

Seems pretty 70s... maybe 1870s...
