When resources are scarce or you’re simply looking for a practical and economical solution, this ingenious invention can get you out of more than one tight spot. With simple and easy-to-find materials, it’s possible to create a portable mini-stove capable of generating enough heat to warm liquids or small containers. Below, I’ll explain how to make it step by step in a clear and safe way.
Materials needed
- 2 cans of tuna (cleaned and dry)
- 1 can of soda
- Screw with nut
- Steel wool or steel sponge
- Alcohol (preferably ethyl alcohol)
- Sandpaper or metal grinding tool
- Tool for making holes (nail, drill or awl)
- Grinder or grooving tool (optional)
Step-by-step instructions for assembling the mini stove
1. Prepare the combustion chamber
Take one of the tuna cans and make several small holes all around the base, forming a circle. These holes will allow for proper ventilation of the fire.
2. Create the support base
Using the beverage can, carefully remove the bottom part (the metal base). Then, draw a circle on the base and make six large holes, approximately 1 cm in diameter, evenly spaced. Also make a hole in the center.
