Hi guys!
Today I'm here with another Redstone contraption: the Secret Slab Staircase. This is awesome if you want to hide your precious items. If you flick that level, part of the regular stairs retract, revealing some other stairs under it, leading to another direction. I tried my best to compact it, and now the whole circuit fits into a 4 x 6 x 5 space.

Materials:
- 18 redstone dust bits
- 8 repeaters
- 2 redstone torches
- 8 sticky pistons
- a few slabs
- 1 lever

Want to try it for yourself? World download is available!

Thank you all for checking this out! I will keep posting!
