Steam supply for experiments in heat
A tin with a press-on lid may be used to make a steam can. Punch two holes in the lid and solder by them one long and one short pipe as shown in the diagram. The long pipe serves as a safety valve and the short single supplies steam to the experiment (by a rubber tube attached).
