Thisn is the UTD Vindicator cannon series. It is separate from the firework nseries. These cannons can be used for several things, base defense, nterraforming, and learning MC physics. All cannon models will be narchived and uploaded on Planet Minecraft, and hopefully added to a ncollection if that feature is ever integrated.
