Minecraft Building TNT Cannon – Check out this video that I created, which shows me featuring one of my creations. This is your standard TNT cannon, but I am using dispensers to automate the loaded. You only need to click the button on the back and watch this thing fire. Each dispenser can hold a ton of TNT, so you get the endless shots without the hassle.
