Steps

A photo showing how to complete this step

Make a hole in the bottom of two cans

Bring your can to a work bench, plastic cutting board, or other surface you can hammer on. Hammering directly on a kitchen table may scratch it. Lightly hammer a nail into the center bottom of a can. Your hole only needs to be just big enough to poke your string through. Remove the nail and use it to hammer a second hole in the other can.
