101 Uses For is popular and let's hope it stays that way. Our second book is presently called 101 tips for self sufficiency; we will certainly dip into this section for ideas. So post away and let's try and get at least one thread up to 101.
for bean-type cans:
fill with water and freeze, when fully hard (about 24 hours) remove from freezer and set to with a sharp punch of somekind and a mahher. I use a large headed masonry nail.
punch out a pattern of dots.
leave somewhere to thaw and drain, stick a candle in it and light. mmmm pretty.
for beer cans:
do the above, but cut out a hole at the bottom like the post just before this one has.

Remove top and bottom lids of the can , flatten out the tin, cut out a "windmill" propeller-type shape - you might be able to do this with kitchen scissors although "tin snips" would be eminently better - twist the "sails" in order to better catch the wind, paint brightly and nail up to a suitable spot around the garden. Scare the birds and make a nice noise too!
