Capillary alcohol stoves

Two sizes, small one is made from a mini coke can, the larger one made from a standard size soda can. I first saw this design on tetkoba's Alcohol Stove Addict youtube channel    • Making Alcohol Stove with only Scissors   He got the design from Fuzzy's Lil' stove at ZenStoves.net https://zenstoves.net/Fuzzy.htm I changed the dimensions a little and found that I did not need any holes pokes, as I never experienced any fuel over flow or uneven flames. The dimensions I use are; 40mm (1-5/8") for the lower portion, and 55mm (2-1/4") for the top of can/top of stove. 10 ports(creases) seem to work well, so I mark and crease the wall every 21mm (since the circumference of a standard soda can in 210mm).
