MAKING FIRE EXTINGUISHERS

We can share this trick with Smoky the Bear.

We can make simple fire extinguishers that work from the pressure created by the production of carbon dioxide.

We'll have to go to a special shop to purchase a bottle that has a small, partitioned compartment inside. Before we had ball-point pens, people used to buy bottles of ink that had a "well" inside. The bottle, with its lid on tightly, could be tipped so that some of the ink would flow into the well. Then, a person could fill his or her pen by putting it into the well, instead of into the main part of the bottle, and taking a chance on getting the outside of the pen all messy. So we need to buy an ink bottle, or another kind of bottle with a well. We also need to make sure it is very clean inside.

Remove the lid, and make a small hole in it. Insert a glass tube or plastic straw -- the smaller the opening the better.

The tube should extend no more than 1/4 inch into the bottle. Seal the fitting with clay, candle wax, or several coats of sealing wax.

Now fill the well inside the bottle with baking soda (sodium bicarbonate). Fill the bottle itself about a quarter full of vinegar. Screw the cap on tightly.

We'll light a birthday candle (in a safe place, of course), turn the bottle upside down, and aim the straw at the flame. The carbon dioxide we made by putting soda and vinegar into the bottle will put out the flame.

Now we'll do it another way:

Empty a tea bag and fill it with baking soda. Fill a bottle half way with a solution of 1/2 vinegar and 1/2 water. Hang the bag in the bottle, not touching the surface of the vinegar-water.

Insert a one-hole stopper into the bottle. Extend a piece of glass tubing, with a short piece of rubber tubing attached, from the stopper.

When the bottle is inverted, the rubber tubing can be used as a hose to direct the spray at and extinguish flames.

To be effective, all fittings must be tightly sealed.

Nozzles made from medicine droppers can be used on the end of the rubber tubing to increase the range of the spray, and different amounts of baking soda and vinegar can be tried to
see which produces the strongest spray.
