First get two Pepsi cans. They need to be pepsi brand. Pepsi uses good aluminum, and the bottoms of the can line up with the liner better.
Next take a brillo pad or steel wool and rub off all the label on the bottoms of the two pepsi cans. It works better if you leave them full for this,that way you dont dent/crush the cans. You can also do the redbull can, although its not necessary because its hidden inside the finished stove.
