Tin Cans?

What can one person or a whole group do with a bunch of tin cans? What good are they? To me there are a lot of good uses for these objects of various sizes. Looking at the picture they can be used for target practice. You could set up for a game of nine pin or something along that route. Tin cans can also be used for planting seedlings for some varieties of flowers and vegetables. Some have even used them to make alarm systems for various reasons. I just thought of this they could be turned into little lights of some kind. Maybe if a person is good with wiring, one could drill little holes in the bottom of the can and put a plug there and on the inside the fixings for the little light bulb. Who remembers the game of Telephone where two cans are joined by a string and a long time ago young kids would act like they were calling their friends like their parents do. As you see I have came up with a lot of uses for old tin cans. In a poem I just published here on Vocal I thought tin cans would make great planters for seedlings of some kind or another. One old idea one could always decorate them somehow for a pencil holder or some sort of holder for some various small objects. If anyone else has any other ideas, please share and if no ideas come to mind one can also take them to a recycling center to be smashed and sent somewhere to be turned into something else perhaps a part of a bike or even a part of a car or turned into a wagon of some sort the kids pull around. There are many options.
