Stupid shop trick, best done with a worn out fine tooth to minimize
risk. Fold a blade like in the video. Fold it again, against the
bottom edge of a workbench. You now have nine very small coils, hand
it to someone unsuspecting and ask them to hold it. Then watch as
they realize they can not let go without it unfolding back to three
coils.

Throwing it to the floor is the quickest way out. Or (with practice)
take it back and revisit the workbench.
