hydrogen gun
This is a really awesome project that should NOT be tried indoors. Yes, it takes some time, but the results are epic. I myself fired at least 4 shots.
What you need:
HCl compound
beaker connected to a plastic tube
big bucket of H2O
any type of metal (preferably magnesium)
cork with hole
sparker with long handle
small plastic bottle
Step 1 pour 100ml of HCl into beaker
Step 2 drop some Mg into HCl, you should be able to see the H bubbles
Step 3 fill the plastic bottle w/ water, hold it upside down in the water bucket
step 4 fill bottle with H
Step 5 slide cork onto sparker
Step 6 insert Hydrogen filled bottle into sparker, the cork should stop air from escaping bottle
Step 7 fire in the hole!!!!!!!!!!!!!!!!!!!!!!!!
Result : My bottle broke
