How to open a box that's locked from the inside
One of the great things about being a magician is the number of lovely objects you get to work with. Beautiful craftsmanship has always played a big role in what we do, and one of the most exquisite creations I've come across doing this work is the Chinese Puzzle Box. These elaborate wooden boxes usually look gorgeous, with lots of different kinds of wood forming patterns, but they are seemingly impossible to open! Sliding and twisting parts of the box will eventually unlock it (though some have 1500 moves!) – and when you do finally get it open, there will normally be a lucky charm inside.
Wooden puzzle boxes are still being made, you can buy them online or from good magic shops, usually with instructions – especially if there are hundreds of moves!
It's probably easiest for you to see for yourself; I found a few being opened on YouTube:
