About this build

This is a compact redstone contraption designed to duplicate TNT. It utilizes a sticky piston, an observer, and slime blocks to repeatedly push and activate TNT blocks, creating multiple explosions from a single initial TNT block. This mechanism is often employed in large-scale demolition or farming operations within the game. Its small footprint makes it highly versatile for various applications.
