Pistons can be powered by a redstone torch directly adjacent to them.

Pistons can be powered by a powered block directly adjacent to them, whether it is strongly powered or weakly powered.

In Java Edition, the wire does not automatically curve to the piston.

If a redstone wire is in a line shape toward the piston.

Rails re-orient themselves after being pushed, similar to when placed manually.

Trying to move both on the same piston using slime blocks does not work, nor does moving them on perpendicular pistons (although the latter temporarily appears to work because of the bug MC-75716).

An exception is when the rail and block supporting it are on two parallel extended pistons at which the rail remains attached.

Rails: as long as they remain on top of a solid face of a block in their new position, and that block isn't moving at the same time.

Structure Void‌ īreaks when pushed, turning to drops when applicable.If the requirements for a block to be pushed are not met, the piston simply does not extend. They also cannot push more than 12 blocks. Pistons cannot push blocks into the void or beyond the top of the map. A sticky piston simply leaves a block behind if it cannot pull it. Pistons can push most blocks, and sticky pistons can pull most blocks, except those listed in the table below. In Bedrock Edition, blocks that stick to walls (such as levers) can be placed on pistons or sticky pistons. See the 'Slime blocks' section below for more details. In addition, when a slime block is moved by a piston, any movable blocks adjacent (not diagonally) to the slime block also moves. However, if they receive a short pulse and don't have a block to be pushed, they pull the block which is 1 block away.Ī piston that pushes a slime block bounces any entity that it displaces in the direction the piston is facing. Also, this causes the block to end up in its final position earlier. These shorter pulses cause sticky pistons to 'drop' their block, leaving it behind when trying to push it with a short pulse. In Java Edition, pistons finish extending early and start retracting if given a pulse shorter than 3 game ticks (1.5 redstone ticks 0.15 seconds). Sticky pistons stick to a block only when retracting, so a block next to the piston head can be pushed aside by another piston and sticky pistons cannot hold falling blocks horizontally against gravity. A sticky piston also pulls the block attached to its head, but not any of the other blocks it may have pushed. It finishes retracting 2 game ticks (1 redstone tick 0.1 seconds) after it starts. Like extending, this retraction starts immediately in Java Edition or, depending on how it was powered, after 1 tick in Bedrock Edition. When a piston loses power, its head retracts. If there is no place for the entities to go, the block pushes inside them, suffocating mobs if the block is not transparent when pushed into the eye height of the mob. Any entities in the path of the extending head are pushed with the blocks. The piston makes a sound that can be heard within a 31×31×31 cube centered on the activating piston. When it extends, it pushes at most 12 blocks. When powered, the piston's wooden surface (the 'head') starts extending immediately in Java Edition or either 2 game ticks (1 redstone tick 0.1 seconds) later or immediately, depending on how it was powered, in Bedrock Edition. Pistons are always placed facing toward the player.

In Java Edition, it is faster to break them with a pickaxe. A piston can be broken using any tool with equal efficiency, and always drops itself.
