These hand boilers are a hell of a lot of fun, even if you aren't stoned.
Not just fun, this is science! Use your body heat to teach a child about distillation! Every child needs to know how to create the water of life.
Honestly, I love my little hand boiler. I keep it next to an arm chair that friends seem to like to space out in.
