So... I had an idea of a combination lock with piston door... But it could


easily be griefed. So I made this super safe storage room thing with a


Combination lock hooked up to a Piston Door. But it doesnt stop! It's also GRIEF


PROTECTED! All done with redstone!




How it works:


You just put in the right ammount of sand in each slot. 1 too much or 1 too


less wont open the door... So you need to have the right ammount of sand. If you


do. The door will open. However... If you dont put in any sand or the wrong


ammount and decide to grief the door... You will drop into lava.





Should I do more Minecraft Projects? Post "Yes" or "No" in the comments please!
