This project is suitable for woodworking beginners and kids. Of course the kids will need supervision if they are going to use any of the power tools he uses in the video. Also you should help them when they use the epoxy to glue the magnets into place. The method he uses to hide the hidden compartment with magnets and the small hole, also works with larger hidden compartments. You just need more magnets. Painting the inside of the pencil holder black was very clever it hides the hole well. The pencil holder would probably look better if you use a more attractive wood.
