If you like to build things and secret hiding places this is one diy project that you will love. The table has a sliding numbers puzzle on the top and the puzzle must be completed in order to unlock the compartment under it. Then once you open that part of the table, inside you will find a mag-lock that will open a hidden drawer on the bottom of the table. This is a work of love but it is an awesome table. Matt2silver shares the instructions on Instructables. Check out the video to see how the secret compartments open. Very cool. You can also check out how to Build Your Own Nightstand With Secret Locking Drawer, which is also pretty cool.
