A ring slides on but gets stuck trying to take it back off.
A kid puts his head through metal slats on a railing, but can’t pull it back through.
A girl gets her body in a clothes dryer, but can’t get back out.

Answer is
Snap fit mechanism.google this.
You will see how we can use tools to snap fit into equipments. Its cost efficient, eliminates extra parts.
Main requirement is that – material should not be too rigid, it should be somewhat flexible. There you go. Our bodies are like that. We can put our leg, hand in some kind of gap, if our hand and that gap is creating snap fit then its very difficult to get out.
In 4th grade, one girl from classroom put pencil in her nose, and it wouldn’t come out. It was funny. It came out somehow.
