How to make a cannon in minecraft pocket edition

On the left side of the TNT cannon, dig at least 10 blocks to the left of the TNT cannon, then do the same to the right side, then fill it with water,then dig straight at least 10 blocks in front and back of the TNT cannon, then fill it with water, then connect each end of the 10 blocks that you dug to form a square, then fill all the gaps with water, then destroy all block inside the square and then fill it with water again.

First you have to outline the whole square of water with cobblestone, then on each corner, put one block high of obsidian, then connect the rest of it with obsidian, then finally you shoot at least 5 to 6 arrows at the top or in the middle of both TNT blocks, warning: You need to shoot in the correct position, or it won't work!

Then watch the arrows fly at least blocks possibly Enjoy!!! Participated in the Minecraft Challenge View Contest.

Did you make this project? Share it with us! Doing so will create a "U" shape that is seven blocks long and three blocks wide. Place your last block on top of the front-left block. This block is the top-left block in the "U" shape. Place the slab at the mouth of the "U". The slab should fit directly in between the front-left and front-right blocks. Pour water into the back of the cannon. At the bottom of the "U" shape, place the water to form a channel from the back of the cannon all the way up to the slab.

This is what will move your TNT forward when you place it later. Place a switch on the back-left and back-right blocks. These switches will function as your cannon's triggers. Leave the middle block blank. You won't put anything here, especially not redstone. Place a line of redstone from the left switch to the end of the left fork. The line of redstone should go all the way up to the last block, including the one you placed on top of the final block on the left side.

Place a line of redstone from the right switch up to the second-to-last block. The line of redstone must go all the way up to the block that comes before the block that's touching the slab. The redstone line should essentially extend the length of the water channel. Place up to four TNT blocks in a line behind the slab. These TNT blocks can go all the way back to the second-to-last block of water, but the source water block must remain. Fire your cannon. When you're ready, flick the right switch, then immediately hit the left one.

This TNT's height will vary depending on how quickly you hit the left switch. If you do very quickly, the TNT will fly straight. Delay it seconds, and the TNT will fly much higher. If you wait too long, however, the first block of TNT will just fly upward and explode. Don't hit the left switch first, or your cannon might explode.

Did you flip the left switch first or not at all? That would cause it to just explode. Not Helpful 95 Helpful Matthew Ray. The redstone makes it so that the other TNTs next to it can activate first before the other TNT projectile can activate in a short delay, so the first TNT can explode and shoot the projectile out.

You could get a silk touch pickaxe and find another stronghold, get the frame blocks, and make your own end portal. If you use a combination of pistons and slime blocks you can, but not sure using just TNT. Not Helpful 1 Helpful 0. Any block that does not explode easily should work well.

If you're using creative mode, bedrock would certainly work. Not Helpful 0 Helpful 0. I did everything percisley yet it just exploded. I flicked the right then the left. Did the slab prevent it or is it just that you had and secretly used a command block?

You probably flipped the switches in the wrong order. You have to flip the one on the side without the extra block first. Not Helpful 0 Helpful 1. Niek Vogelaar. Simply add more TNT in your cannon. Also you can find mods, although they do not always work.

Why does the TNT explode in the air and why do you need to make it from obsidian? Obsidian cannot be broken with TNT. If you want to blow up your cannon, then make it out of wood or something similar. When TNT gets lighted, it takes time before it explodes, probably it was in the air when the time was over. It depends on how you made your cannon.

Maybe you can add a few blocks on top so it goes more forward than up. Include your email address to get a message when this question is answered. By using this service, some information may be shared with YouTube. When reloading your cannon, be sure to flip the levers off.

Otherwise, they will begin to explode immediately! You can switch the levers with buttons to prevent this from happening. Helpful 41 Not Helpful Helpful 37 Not Helpful You don't have to have your cannon sitting in the middle of nowhere.

Try incorporating it into a building. Helpful 31 Not Helpful Helpful 17 Not Helpful 7.
