You’ve already created a soda can burner, but now you need a pot support. There are as many pot support designs as there are people to design them so use what you prefer. With that said, here’s the one I use for my soda can stoves.

Step 2: Shorten your strip to the circumference of your pot support, plus a few inches
Step 3: Loop the strip and connect ends

Step 5: Burn the twisty ties (if necessary)
