Objectives:
The aim of these experiments is to assemble a homemade fire extinguisher helping home of the reaction produced by the baking soda and vinegar.
Theoretical Foundation:
A fire extinguisher, fire extinguisher, or fire extinguisher is a device used to extinguish fires. It consists of a metal container (bottle or steel cylinder) containing a fire extinguishing agent under pressure, so that by opening a valve the agent goes through a hose which should be directed to the base of the fire. They generally have a device to prevent accidental activated, which must be disabled before using the appliance.

According to the extinguishing agent can distinguish between:
Water extinguishers (charged with water or a foaming agent, the latter no longer in use by its low efficiency).
Dry chemical extinguishers (MPT: fighting fires of Class ABC)
CO2 extinguishers (also known as dry ice or carbon dioxide) Class BC fires.
Fire extinguishers for metals (only valid for combustible metals such as sodium, potassium, magnesium, titanium, etc.)
Halon (halogenated hydrocarbon, now banned worldwide because it affects the ozone layer and have permission to use until 2010.
Instant Multiextintor (before extinguisher explosion) is a rescue tool Fire professional use, consisting of an elastomer container containing flame retardant, and houses in its interior an element attached to a pyrotechnic igniter cord. Which on contact with fire, broken container and creates a bubble devoid of oxygen that puts out the fire, while cooling the area within five meters.
materials:
Sodium bicarbonate
paper napkin
A small plastic bottle of dry
Perforated cork
a straw
vinegar
Sewing thread
procedure:
1. Within the napkin introduce 4 tsp bicarbonate of soda
2. With the help of thread and tied shut the bag-shaped napkin
3. Enter 5 tablespoons of vinegar into the bottle.
4. Suspend the bag of baking in the bottle so that it hangs and never touch the vinegar.
5. We take the cork or clay and put the straw in the mouth of the bottle.

6. To operate the extinguisher you just have to shake the bottle, covering the straw with your finger and holding the bottle at the same time, to mix baking soda with vinegar (without uncovering the straw). Remove your finger and project the gas coming out of the bottle over a candle.
