Here are some if the things I do with them.
By cutting square holes out of the bottom of a can, you will have enough metal left over to screw the can down to another surface.
By screwing two of them to the top of a rectangular wooden form, you have created the hollow portions of a j tube rocket stove core.
Position this in an outer form and cast around it with a CementAll, perlite, and rockwool mix.
Burn out the insides and you have your core.
Cut off both ends of a can, place it in a square form 7" tall, and cast around it with the same mix.
Repeat this until you have enough to stack into a riser.
Cut off both ends of a bunch of cans and and tape them together, end to end to create lengths of duct work , chimney, or concrete forms.
These fit nicely around 6" duct, so they can mate with or substitute for that sized duct in many applications.
Using a long driving bit, run screws through the bottom of the can into a wall stud.
Hang cloths on it, or add more cans on adjacent studs, level with the first, and secure shelving across them.
The open cans are cloths hooks or shelf brackets with storage built in.
