Fully-Functional LEGO Combination Safe

You don't need to spend $20-$40 buying a combination safe for your kids to tinker with. Just follow Merijn van Wouden instructions on how to build one using LEGO pieces. Video after the break.
I've seen a few combination safes on youtube, but they all used an at least 5 times bigger mechanism than this one.[via Brothers-brick]
