Not sure how big those are, but you can probably make tea light holders from them. Paint the cans or Decoupage them to make them attractive, then place a tea light in them. You might want to Use battery operated tea lights for safety sake. If there is enough room in the cans it might be nice to put some decorative tiny rocks in them or sand.

First cut the bottom out, clue them in some kind of design, and hang it on the wall. Good Luck!

I melt them down in a forge and cast aluminum objets d'art

Maybe mini planters- try putting magnets or clips on to hang them, or if you're really crafty put them on a wooden dowel in a spiral ;)

I shingled a Little Free Library and made it look like dragon scales.
