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). When the tin leaks or becomes rusty the similar lid may be transferred to a same tin.1922_physics.png
