Learn about the inner workings of a combination lock as you build one with your own two hands. Step-by-step instructions make it easy to slide each piece into place and create your own custom combination. But building it is only half of the fun. Hide a secret message inside and share your code by means of a riddle. Use the metal shackle to turn it into a padlock for keeping a special cupboard locked.
There’s even a slot for coins on the side – You can turn it into your own high-security coin bank!
