Next you will want to place 9 redstone repeaters so that they are facing the front of the cannon. Go back to the front of your cannon, and place two redstone one block away from the half slab (on the blocks you just placed in Step 3). This, in the long run, can save resources in survival (especially if you only have 1 water bucket on you while raiding). Go to the back of the cannon, and place a block over top of the water source. This next part is optional, but I personally find it useful so that I don't accidentally place TNT on the water source. This pillar will be 11 blocks long (1 block longer than the rest) by the time you reach the back.Ĭonnect the right blocks with the left along the back of the cannon. Turn, and continue building this layer all the way to the back of the cannon. On the right side of your cannon, place two blocks along side of each other 1 down from the wall you built in Step 2. You want redstone all on the left side, but NOT on the block to the side of the half slab! The half slab will be powered another way, so don't worry about that.

On the opposite side of the wall you just built, place redstone all along the side. This will prevent the TNT from shifting too far out of place, and will keep the TNT inside the water so the water will absorb the block damage from TNT. Step 2 Preventing Mishapsīuild up the right side of your cannon so that is is two blocks tall instead of one (right side meaning-stand in front of your cannon and face the back of it). Now you can place a half-slab right after the block the water ends on. If you counted your blocks out correctly, your water should stop 1 block away from the edge. For this step, you will want to make sure that your water is flowing TOWARDS your kill target. Place your water source at the back of the blocks, inside the little barricade you just made. You will now want to place your water source.

Do this process for the right side as well. Continue placing the remainder of the 10 blocks. At the back of your 10 long horizontal pillar, place 1 block to your left, and another block on top of that. Place 10 blocks down (1 block wide) on the ground making sure that it's pointing towards your kill target. Since water flows 8 blocks in a straight line, we will be making our cannon 10 blocks long (we will need 1 extra block on each end). Overview of how customizable and efficient this cannon is.
