Piston in Minecraft

Pistons can be either crafted or found in the Overworld and are naturally generated as a part of jungle temples and ancient cities. Players can also craft pistons with 3 wooden planks of any kind, an iron ingot, redstone dust, and four pieces of cobblestone.

Pistons are redstone-powered blocks that can push blocks when activated with a redstone signal. Since pistons can also push entities, any entities in the path of the extending head are pushed with the blocks.

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. When a piston loses power, its head retracts. Pistons do have some limitations, they cannot move the following blocks :-

1. Barrier Blocks
2. Beacons
3. Bedrock
4. Command Block
5. Obsidian
6. Crying Obsidian
7. Conduit
8. Enchanting table
