Maybe get the cans with no seem on the bottom , they only have the seem on the top with the pull tab too open , the seemed bottomed tins should only be heated up in a sauce pan with water around the tin to stop it heating up too much you can get some fare sized tins made that way now I'm thinking . Cheers for the videos.
It turns out the cans I used have no seems on the bottom. I just bought the same cans new and I can see they don't have seems on the bottom. The ones I used are all carbon-ed up and I don't want to handle them. I'm going to try deffer-ant fuel. What happened was the fuel boiled over into the bottom of the stove. Thanks for watching.
