Bouillant de Franklin (Hand Boiler): reversible liquid-gas phase transition device made famous by Benjamin Franklin who was one of the first to describe the physics of its operation. The boiling point of dichloromethane is slightly below body temperature - heat from a hand increases pressure in the bottom bulb pushing the green (dyed) liquid through the glass pipe to the top. This one in my collection is a vintage handmade version from France currently on display at the LA Central Library’s Gett

Boiler Pen: a miniature “hand boiler” is built into the top of a pen in this odd vintage item in my collection. The boiling point of dichloromethane is slightly below body temperature such that heat from from a finger and thumb will increase pressure in the bottom bulb which then pushes the purple (dyed) liquid through the thin glass pipe to the top. Heating the top bulb will hasten the return of the liquid to the bottom. Such glass devices demonstrate a reversible liquid-gas phase transition an
