This instructable will show you how to easily make a functional rocket stove from recyclable cans for almost no cost.
Items you will need:
4 – Regular soup cans (Standard 8oz Soup cans)
Insulation material. You can use sand, dirt, ashes, foam, any insulator.
Hammer and nail (to punch starter holes)
Pliers (makes bending the metal a little easier, but not totally necessary)
Remove all labels from cans.
Take one of the four soup cans (soup can #1) and trace the shape onto No.10 can. I cut my hole slightly above the bottom of the can to make it easier to avoid dealing with the bottom of the can when cutting and shaping the hole. Seems to have worked out fine. I then punched a number of holes into the circle so I could get the tin snips in there to cut the circle out. Punching that many holes turned out to be a waste of time as a single hole would have been fine. The tin snips cut through the can quite easily.
