Step 2: Boiler1. First you will need a small soup can and a drill bit just slightly smaller then the tubing you plan to use. In this step we will drill 2 holes into the soup can to empty its contents (pick a can of something like broth or tomato paste to make emptying easier). The 2 holes in the end of the can will serve to hold a small ...
