AN INTERESTING EXPERIMENT.
Ke-written from Experiment Done at School,
Take any tin —preferably a clean benzine one if possible—and pierce two holes in the top. Put in water to the depth of about one-and-a-half inches, and with one hole sealed, heat until all the steam is driven off. Seal the other hole and set aside to cool. In about five minutes tho tin will begin to cave in on all sides with much creaking and banging.
Tho reason is that the heavy air outside is able to push the tin in because tho air inside is light and can only offer' slight resistance. —From Tan E. Allan, P. 0. Kesidence Cambridge.
