The Piston Platform in-game.

Piston Platforms are testing elements in Portal 2. They move vertically in 128 unit increments, up to a limit of 384 vertical units. Piston Platforms can be placed in goo (to make a retractable bridge for instance). When retracting, cubes or the player will be destroyed if they are caught under the Platform. If no inputs are added, the Platform will move to the second position when the player stands on the top surface.
