Elementary Gas-Burner
Fill an old round tin box, at least two inches high, with sawdust and pieces of blotting paper. Close it as well as possible, and introduce a small metal, or glass, tube in the lid to a depth of about one-third of the box.
Make the joint tight with putty. Put this box on any two supports and place the flame of a lamp or candle underneath it.
Soon the overheated sawdust and blotting paper will evolve vapors of alcohol and combustible gases. Approach a lighted match to the upper end of the tube and you will see the gas ignite and continue to burn.
