How to open can without can opener

For the launch of the book, we created a series of five short films to showcase different techniques that would be vital for surviving the immediate aftermath and rebuilding the capability of your post-apoclyptic society. This first one in a series of three shows how to open a tin can without a can opener, or any other tool. If you understand a little about how the tin can is constructed, you can exploit a neat trick to open the lid very easily. Also see (2/3): How to start a fire with everyday items and (3/3) How to make a gasifier stove, as well as How To: Electrolysis.
