Kidz Lab: Combination Lock
Do you like solving puzzles? Do you have something to hide and don't want anyone to see it easily
The Kidz Lab: Combination Lock lets you build your own multi-purpose combination lock and you can determine the combination yourself. Lock doors, hide secret messages or you can even keep your money safe in the combination lock. Have someone else make a combination and attempt to crack it yourself.
The combination lock requires assembly. Adult supervision is advised for assembly.
