So the story follows that a professor posed a puzzle to his class:
“How did I tighten a bolt through a stick inside this bottle?”
He allowed his students to take the bottle home and figure it out, allowing them to write their name on the stick once removed and having them reattach the bolts to the stick once back inside the bottle.
One of his students struggled with the concept for 10 years and consulted some ‘expert’ help.
The method is actually quite amazing.
Did you figure it out?
