Step 1: Materials

Picture of materials
obsidian, flint and steel, tnt blocks, a slab, and a bucket of water.

Step 2: Sturdyness

dig a 1x3 hole in the ground and fill it with obsidian blocks. That way, when you use the cannon, it won't blow itself up!

Step 3: Framing

surround the blocks with more obsidian and leave one corner uncovered. This will keep things inside the cannon and will prevent surrounding blocks from exploding.

Step 4: Ammunition holder

Add your slab on the end part of the obsidian. this will hold your ammo and will keep the engine( water) inside.

Step 5: Engine

Add your bucket of water to the other end of the cannon. this will help push the tnt distances.

You just don't know how to operate it. That is why
Ok now it is not working, since the water is there your TNT will not explode. And if you don't have water there, then the TNT on top will not move it will just explode
Like it but just get annoyed when it doesn't really work. Most the times it does work but I don't like it when it goes a short distance...
Nice! Love it! Was battling my friend, and i used this an blew him up!!! You can also make big cannons to use for longer distances and more explosions
Does it still work in 0.8.1
