Pistons have been part of Minecraft since the Beta 1.7 update in 2011, when Mojang added them as redstone-powered blocks that push other blocks, with sticky pistons able to pull them back. They quickly became central to player engineering, powering hidden doors, elevators, farms and elaborate traps shared in tutorials and gameplay videos. Because the extension sound is so closely tied to that moment of movement, it spread beyond the game itself into edits, memes and soundboards, where it now signals a machine activating or a secret being revealed.
