The cannon is sometimes used to launch people into the sky. It's also used to launch TNT over long distances for blowing up certain things.
- In "Assembly Required", if Jesse visits Redstonia (Determinant), he/she can see a TNT Cannon built by the Old Farmer Man.
- In "A Block and a Hard Place", Jesse can choose to build a TNT Cannon to get inside the Wither Storm. (Determinant).
- In Minecraft, TNT Cannons are usually surrounded with Water so that the explosion doesn't harm the Player and destroy Blocks.
- However, this safety mechanism is not seen in Minecraft: Story Mode.
