"PROPANE Tank" Even after removing the valve there is still fumes inside the tank, filling with water diminishes the size of the air gap. (Explosive area containing propane gas, and now oxygen) This allows you to safely apply an open flame to the tank.
If you want to try it without filling, make sure you have a video camera, and post it up after you get out of the hospital for everybody.
