How Do I Create a TNT Cannon In Minecraft?

TNT cannons, while not exactly peaceful, can be a fun and creative way to add some explosive excitement to your Minecraft world. 

They can be used for various purposes, from blasting through tough terrain to creating elaborate traps or launching yourself across the map. But how exactly do you build one?

This guide will take you through the steps of constructing a simple yet effective TNT cannon in Minecraft.

Materials Needed:

  • Stone (or any other buildable block)
  • Stone slabs (any type)
  • Water bucket
  • Redstone dust
  • Redstone repeater (optional, for extended activation)
  • Lever or button
  • TNT (of course!)

Building Steps:

  • Crafting the Base:
    • Start by creating a rectangular base using your chosen building block. The size can vary depending on your desired power and complexity. A good starting size is 9 blocks long, 3 blocks wide, and 4 blocks high.
  • Water Source and Launcher:
    • On one end of the base, leave a 1×1 gap at the bottom. Place a water source block in this gap.
    • On the block directly above the water source, place a stone slab. This will be the launching point for your TNT.
  • Redstone Circuitry:
    • Now comes the fun part: the redstone! Run a line of redstone dust along both sides of the base, starting from the block opposite the water source and stopping one block short of the end.
    • Place a redstone repeater at the end of each redstone line, facing inwards towards the base. You can adjust the repeater direction later for customized timing.
  • Trigger and TNT:
    • Connect your chosen trigger (lever or button) to one of the redstone lines near the repeater.
    • Place your TNT directly behind the stone slab launcher, ensuring it doesn’t touch the water source. You can add up to four TNT blocks for increased power.
  • Testing and Customization:
    • Once everything is connected, activate the trigger and watch your TNT cannon launch!
    • Experiment with different TNT placements and redstone repeater settings to fine-tune the power and direction of your cannon.

Additional Tips:

  • Safety First: Be mindful of where you aim your cannon, as TNT explosions can cause unintended damage.
  • Building with Blast Resistance: Consider using obsidian or other blast-resistant materials for the cannon’s base to prevent accidental self-destruction.
  • Advanced Designs: This is just a basic cannon. You can find more complex and powerful designs online that incorporate additional redstone components and features.


Remember, with a little creativity and these helpful steps, you’ll be crafting your own TNT cannons and adding explosive fun to your Minecraft world in no time!
