Steel Can Heater/Stove! the 'Cotton Ball' Heater/stove! - Easy DIY




About: hi there. on this instructable channel i'll be covering all types of DIY solar power projects (as well as off-grid/survival/green living projects) that are easy to make out of readily available products and ...

in this instructable i'll show how to make a heater/stove out of a couple of small metal cans and some cotton balls


Step 1: Watch the Instructional Video...

Step 2: Read Description...

Homemade Steel Can Heater/Stove! The "Cotton Ball" heater/stove!. Easy DIY. lots of heat. cooks great. items needed: two small metal cans, dirt, cotton balls and isopropyl alcohol. great for any off grid situation, SHTF, power outages, camping etc. or everyday use.

Step 3: The Materials Needed...

1.) 2 small metal cans (one slightly wider than the other)

2.) cotton balls

3.) 70% isopropyl alcohol (rubbing alcohol)

4.) dirt

5.) optional: 2 or 3 extra cans that are slightly taller than the other 2 (used for making stove)

Step 4: Construction...

first step is to place one can inside the other. then add dirt between the 2 cans. should look like the pic above.

Step 5: Then Drop in a Few Cotton Balls...

Step 6: Then Add the Alcohol...

then add the alcohol and fire it up...

Step 7: Puts Off a Ton of Heat...

2 of them kept the surrounding area quite warm. note: always take care when using these. treat them with the same respect that you'd have for a candle or an alcohol lamp.

Step 8: Here's the Stove Conversion...

to convert it to a stove just put 2 or 3 larger cans around the heater (see pics above) and place a pan on them. i only needed to use two cans. it made a stable "burner grate". note that since the flame is centered under pan, it's best to use a cast iron pan (because those spread out the heat). cooked an egg as if it was a standard stove burner.

Step 9: Have Fun Making and Using It!

    You van put dirt under it, but it's not necessary, as all the heat is concentrated at the top of the interior can. The alcohol vapor is what is burning.
