It is really small, yet a good alcohol stove. It has no moving parts and it's made from 2 components, being very strong and durable.
The materials are:
a gas stove's tap's mount piece,
an old lamp,
and, of course, the alcohol.
To assemble it just remove all the lamp's socket glass except the bottom black glass wich holds the contact, put it in the stove's piece and secure it with wire. To use it just put the pan on the stove, fill the lamp's socket with alcohol and start it up.
