Sticky Piston block in Minecraft
A Sticky Piston pushes a block like a piston and pulls it back when it retracts.
It is made with the Crafting Table from Piston and Slimeball. It is mined with a pickaxe.
What it does
A Slimeball on a Piston makes one. It moves up to twelve blocks in a line and pulls back the block touching its face, which is what hidden doors, bridges and flying machines rely on. Some blocks, such as obsidian or glazed terracotta, cannot be pulled.
