Build a 2×2 sticky-piston door that hides flush in a wall and opens on cue.
Every great lab has a wall that isn't really a wall. Press the hidden button and watch it swallow itself.
- New skill Building a 2×2 piston door
- Level 6 · Inventor's Lab
- Difficulty Intermediate
- Mode Creative
- Time 45–60 min
- Ages 13+
What you’ll build
Cut a doorway into a thick wall and fill it with blocks held by four sticky pistons, so the door sits perfectly flush. Wire it first to a lever, then upgrade to a hidden button and a redstone torch, and put it through a tough reliability trial.
Finish line: Your 2×2 piston door hides flush in the wall and opens on a hidden button every time you test it.
Bonus challenge: Make it two-way: add a pressure plate on the inside, wired to the same torch block, so you can walk out without hunting for the button.
You’ll need
- Sticky pistons
- Wall-matching blocks
- Redstone dust
- Redstone torch
- A lever
- Buttons
You choose
- My door's code name
- Disguise blocks that match my wall
- Secret trigger: hidden button, pressure plate or
Stuck?
- One piston not moving? Make sure dust or a powered block actually touches it.
- Door opens only briefly with a button? That's normal: a button gives a short pulse. Run through fast!
- A stone button gives a shorter pulse than a wooden one, so try both in the race test.
