looks like fun a worning from one of those sites
[edit]Warnings
This stove is designed to burn only denatured alcohol or absolute ethanol. It would be explosively dangerous to use gasoline, white gas, camp fuel, kerosene, or any other fuel in this stove. Isopropyl alcohol (rubbing alcohol) will not work either.
The flames from these fuels are practically invisible and if the fuel is spilled near the flames, this can result in a fire catching and spreading very quickly. Handle with care and be sure to have no flammable material around the area of the stove. Do not use a stove such as this near peat sites or tinder-dry vegetation.
Ask for help from an adult, teacher or parent with cutting the cans if you are a kid or if you do not feel confident in cutting it yourself. Take care not to slip with the knife or scissors while cutting.
The cut edges of the cans can be sharp. Use caution when working with them.
If you have too many large holes in the top, the fuel will not burn cleanly.
Do not keep your hand too close to the heat or flame when lighting. If the stove becomes too hot while you are lighting it, take a rest until it cools down enough.
Be careful not to burn yourself.
Be careful with sharp objects used to make the burner holes.
We use one that uses one burner folds for a back pack and uses fuel cans from a chaffing dish we just put the top back on to put out the fire..
