Answer 1

You will need the following things :

1) a hollow glass tube or a eye dropper

2) a big glass bottle

3) a bottle of vinegar

4) a box of baking soda

6 ) a rubber or cork stopper that fit the big bottle

7) paper towel and a rubber band

8) water


First thing to is remove the rubber squeeze bulb on the eye dropper and keep the glass tube

and make a hole slightly smaller than the glass tube in the rubber or cork bottle stopper and insert the glass tube in the stopper until the tip of tube come out of the stopper . ( Do this slowly ; so not to break the glass)

Put baking soda on the sheet of paper towel and attract the corners to the other end of the tube to the rubber stopper securing with the rubber band

than fill the big bottle: 1/3 full of vinegar and the other 1/3 with water leaving the bottle about half full

Than carefully insert the rubber stopper on the big bottle with the bag of soda hanging above the vinegar water solution. Make sure it a tight seal on the bottle

when you ready to use

Tip the bottle over and wait a minute or two than the water will shoot out of the tip

and you have a working Fire extinguisher
