About this build

This compact gravity TNT cannon is designed for efficient and reliable explosive projectile launching. Utilizing a stack of dispensers, it feeds TNT into a water stream, where a sticky piston precisely positions the charges before detonation. The extended redstone repeater line allows for timed detonation sequences, ensuring maximum impact. Ideal for fortifications, clearing terrain, or creating devastating traps, this build offers a powerful solution in a small footprint.
