Create the Lab world and hide your HQ behind a secret piston wall.
You've just been named chief inventor. Job one: build a lab so secret your own family walks right past it.
- New skill Building a hidden piston entrance
- Level 6 · Inventor's Lab
- Difficulty Intermediate
- Mode Creative
- Time 45–60 min
- Ages 13+
What you’ll build
Start a brand-new Lab world and hide your HQ inside the most boring disguise you can think of. Then build a secret wall from sticky pistons, wire it to two hidden levers so either one shuts it, and test it until it works every single time.
Finish line: Your Lab hides behind a boring disguise, and its secret piston wall opens and shuts perfectly every time.
Bonus challenge: Add a fake entrance with a door that leads into a broom cupboard and a sign saying "Definitely Not a Lab". Spies will love it.
You’ll need
- Sticky pistons
- Levers
- Redstone dust
- Wall-matching blocks
You choose
- My lab's code name
- Its boring disguise (haystack, cow shed, boulder, giant cake…)
- Where I'll hide the outside lever
Stuck?
- Top piston won't move? The dust must run straight into the block behind it, not just past it.
- Pick ordinary blocks for the wall: sticky pistons can't move obsidian and a few other blocks.
- Wall stays shut with one lever off? That's right: both levers must be off for it to open.
