My dad used to do this for use kids when we finished up a gallon of Vermont 
Maple Syrup. He'd boil a bit of water in the can. Then put the lid on tight and 
run cold water over it. The air pressure would crush it like CA like to do to 
our old cars. It was great fun. Too bad the syrup producers are switching to 
plastic containers.
