This is my science fair project by Faisal Al-Wabel i

Step 1: Why I Chose This Area of Science

I chose this project so it could be helpful for us and the community from self defense or if we went camping and something suddenly happens we can use the Propane gun.

Step 2: The Problem

Saudi Arabia is the only country that have low propane torch supplies so it will be hard and challenging to find stores or places that sells them.

Step 3: The Hypothesis (or the Prediction)

Propane Gun: Will the gas dissolve in time when we release the fire?

Step 4: Research

Propane Gun: We know that this weapon/gun uses a propane torch and some PVC Vinyl clear tubes that connects the torch and the bottle at the end that fires the gas and fire but plastic bottle in the end might melt and shrink since the effects of fire and plastic is shrinking and making it small, but after a few propane shots it will shrink 25-30% but after that it will stop.

Step 5: My Testing Method

Propane Gun: We started by trying to ignite the propane torch

Then we connected it with the clear vinyl tube After that we attached the PVC tube to the torch and the clear vinyl tube to make it look like a gun and easy to handle Then we decided to attach a bottle at the end to make a loud noise.
