This instructable will show you how to easily make a functional rocket stove from recyclable cans for almost no cost.
Items you will need:
1 - No. 10 Can (Standard restaurant size can. Mine was a pineapple chunks can from a local pizza parlor. They gave it to me free.)
4 - Regular soup cans (Standard 8oz Campbell's Soup cans)
Insulation material. I used Perlite. It's cheap and available at any garden center. I had it on hand for my garden. You can use sand, dirt, ashes, foam, any insulator.
Tools:
Tin snips
Hammer and nail (to punch starter holes)
Pliers (makes bending the metal a little easier, but not totally necessary)
File
Gloves

Signing UpStep 1: Mark and Cut hole in No. 10 can
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.
I used a pair of needle nose pliers to bend the edges of the hole back to get the final shape, but in retrospect I would have probably just relied on the sharpie outline and cut the hole wider to begin with. I was somewhat conservative when cutting and widening the hole took some effort. Later can fittings were made easier by just cutting the hole to the right size to begin with. I was afraid of cutting too big to begin with and therefor spent a considerable amount of time fidgeting with it.

I was told kiln cement is the way to go. Comes in putty form and dries out and can handle up to 1300 degrees Celsius. Will check it out and report if it is a success.

I haven't measured the temperature but mine cooked two rashers of bacon in the same time it took to cook on the gas stove in the kitchen.
You could easily cook a bacon and egg breakfast on this stove. I think bigger meals in a dutch oven would be a problem especially due to the requirement of watching the fuel supply into the stove for a long period of time.

This instructable is a little old now so I don't know if you're still watching the comments. The problem I have is that the Perlite I am using is a range of different sizes and some of it is very small and nearly a powder. How do you stop this stuff pouring out the cracks. I made one stove like this and when I encountered this problem I used a steel putty. That was pratley's putty that dries out to be of near steel strength. The problem is that it gave of black smoke from the chimney seal that I was not comfortable cooking food with. So I am now set up to try this again and any suggestions would be welcome.
Currently I am thinking of using aluminium foil with some wire to hold it in place. Any thoughts?
Any suggestions would be most welcome.

Thanks for posting this.
(works well cooking hot dogs)
Have you considered a handle to carry it, or in case it needed to be moved while still hot? You wouldn't want it over the chimney...
Can't wait to see it.
