Special pistons

Place a sign touching a piston and put its tag on line 2. Power the piston with redstone. Mechanic IV unlocks Crush and Bounce; Mechanic V unlocks SuperSticky and SuperPush.

Tag	Effect
[Crush]	Breaks the block in front of the piston.
[Bounce]	Launches entities in front of the piston.
[SuperSticky]	Pulls a line of blocks from up to eight blocks away.
[SuperPush]	Pushes blocks up to four blocks farther.

Movement is limited to 12 blocks. Protected blocks, block entities such as chests and signs, unbreakable blocks, and materials including obsidian cannot be moved or crushed. Test the mechanism in an open area before incorporating it into a build.
