Black Powder and Carbide Cannon Fun!!

This is a 8" Black powder cannon I found at work. I thought it would be fun to buy some powder and try it out. So we bought some pyrodex powder (black powder substitute) and headed out to Sid's house.
This is our fourth attempt, the first couple were pretty sad. We started with 10 grains of powder and worked our way up to this shot with 30 grains. Please forgive the poor quality videos, they were taken with our cell phones because we left our cameras home.



This is our fifth shot with a 40 grain charge. It is really loud, and lots of fun. We decided to stop at 40 grains before we overcharged and had an accident.




This is Sid's Carbide cannon. After shooting a bunch of times he started putting a potato slug in the barrel and shooting it. It was pretty cool, and a lot safer than the Black powder cannon.
