Introduction: Bottle Gun Under $0.5

Its clear from the topic that this instructable will teach you how to make a really powerfull gun from scrap.

You can use this loud bang in hiking trips if you are lost so that you can get back to your team.

First of all its a low cost project which will be costing you around $0.5

Oh yeah!! only half a dollar.

Dont believe????? then check out the materials!!

It actually works on the gas formed by reaction between baking soda and vinegar[ NaHCO3 + HC2H3O2 → NaC2H3O2 + H2O + CO2↑]

Come on lets get started....

Step 1: Materials

1. Champagne cork or something similar to it.

Step 2: Lets Fire It Away.....

1. Put 2 spoons of baking powder in the bottle.

2. Ask someone to pour about 5 spoons of vinegar in the bottle.

3. Immediately press the cork in the mouth of the bottle.

4. Shake the bottle and aim the cork away from any living being.

Out goes your cork with a huge bang!!!!

1. Do this steps outdoors.

2. Do not aim at anything valuable or any living being.
