I am having fun trying to build an alky stove two so far.

I'm thinking of trying a soda can stove inside a larger can as a wind screen.
I plan to simply use a larger can to place the stove inside of the same as some of the wind screens I see out there only smaller I'm not sure how small I can go with this, I have an almond can which would leave about a half an inch gap.


1 should I make vent holes?
2 how tall should the wind screen be?
3 does anyone even think it will work? LOL
4 how much space should I have between the two cans?
