Just setting up this stunt could get a guy killed.
Here’s a fun one:
Fill a plastic soda bottle with gasoline.
Take small round candle, (or any kind for that matter)
place the lit candle in a small cardboard box with the top “vented”.
Place the bottle on top of box.
Place away from your person or others.
Ventilate bottle with rifle round of choice.
Makes for a BIG flash fire.
Oh yea, place away from flammable objects........
Happy Fourth.
