Pistons are used to push between 1 and 12 adjacent blocks forward 1 space. It can also push players, mobs and many objects (specifically, "entities"). Sticky pistons can be used to push OR PULL a single block 1 space. Pistons can also block the flow of fluids when extended.
Pistons can be horizontally facing or vertically facing. If a piston is vertically facing and is retracted with a gravity-affected block on top of it, that block will fall one square to rest on top of the piston.
You can activate and control pistons by using redstone circuits.
Pistons cannot move obsidian, bedrock, or objects that have additional data attached to them such as signs (they store the message), chests (stores contents), dispensers (stores contents), etc. Pistons can move other pistons if they are not extended.
