Plus that aluminium is easer to form into shape.

Plus,, that Ward Dossche' claim that drink cans are almost all made of
steel here in the EU, does not match the facts. The beer can of a well
known brand I have here in front of me is made of aluminium. Including the
lid and the clip.

Back to the experiment: The composition of the can is relevant. Steel and
aluminium have different heat properties. Also, the wall thickness of the
steel container may differ from that of an aluminium container.

Ground rule is change only one thing at the time. So when comparing
different liquids, use the same containers. Same size, same composition...


Cheers, Michiel
