A fire extinguisher is a device used to reduce the start of a fire. In any closed place it is necessary to always have one at hand to be prepared in any emergency situation. But, you can also learn how to make a homemade version to use, for example, to put out a stove or charcoal stove.
In addition, by doing so you will be able to check the chemical reaction of some elements that come into contact, such as baking soda and vinegar, a combination with which you can also inflate a balloon.
However, beyond curiosity and experimentation, this device could not in any case replace a conventional fire extinguisher; since in case of fire, it is never convenient to improvise.
- a bit of thread
- a paper napkin
- straw or straw
- A perforated cork stopper (or plasticine)
- small water bottle
- Sodium bicarbonate
- Vinegar
Process
1. Put 4 tablespoons of baking soda on a paper napkin. Close it and tie it with a thread. It should be well attached.
2. Add 5 tablespoons of vinegar into the bottle and a small amount of water.
3. Place the napkin with baking soda inside the bottle and let it hang without coming into contact with the liquid, making sure that part of the thread remains on the outside.
4. Put the cork or putty in the bottle cap, with the straw inside. This must communicate the interior part with the exterior.
5. Shake the bottle (covering the straw) so that the baking soda together with the vinegar produce a chemical reaction that generates carbon dioxide and the effervescence fills the container.
Test it!
Uncover the straw and you will see how the carbon dioxide that will put out the fire comes out.
What is the explanation of its operation?
The carbon dioxide produced, having more mass than air and accumulating with a certain pressure, displaces oxygen from the air. Without oxygen, combustion will not be generated and the fire will go out.
