Just because it's small doesn't mean it can't do what the full-scale model can do. It's pocket cannons; which you can hold in the palm of your hand. Fully functional black cannons in steel construction can send off a blast, just like the large military artillery they are modeled after.
There are families who use
during family events, like the celebration of Veterans Day.
Some say the historical relevance of these cannons make them a highly desired possession. They want to own one, and the large caliber ones found at 4th of July and celebratory events are next to impossible to obtain. So the mini cannon is the next best thing.
A lot of the pocket cannons operate with black powder, but they recommend that you use tissue to diffuse it and that you don't use any type of projectile. There are a few places where you’ll need to check the local laws regarding black powder cannon, even in mini form. Those places include Michigan, New York, New Jersey, Illinois and Canada. People who live in those areas should familiarize themselves with the laws related to these slices of history.
