Hey, kids! Finish off March break with a cool foam core wizard puzzle box project!
Of course, the problem with puzzle boxes - particularly ones made of a lightweight substance like foam core - is that if anybody really wanted to get inside, a couple of tricky sliding shapes isn't going to stop them. One good stab with a box cutter, and all your precious secrets come tumbling out. And that tiny lock on your diary? Not exactly sibling-proof. But that's not the point: puzzle boxes are about the fun of physical puzzle solving, not security for secrets. Don't overthink it. Make yourself a cool box.
