my dad taught me how to make this amazing water gun today so i thought i would put it on instructables for this project you will need
an old fire extinguisher (pre 1990's)
an air compressor that can go up to 120 psi
Step 1: find supplies
we went to a garage sale today and bought a perfect fire extinguisher for a $ 1.50 but im sure most people wont be that lucky so i would look at garage sales and on craigslist and other places for one it should be a large fire ext. i think mine is like a 2 gallon .
