Spy Games with Buttons
RAY: There were a lot of things they could have done. They could have applied some adhesive making them difficult to turn or they could have put some kind of a locking pin. But what they thought of was even better. They made the threads.
TOM: Left hand thread.
RAY: Exactly. So when the Germans twisted the buttons, they in fact didn't come off, they got tighter. And after they failed in a few attempts, they gave up on it because they just figured out, they're not using that trick anymore.
RAY: So who's our winner?
TOM: The winner is Gregory Spar from Hazelton, Pennsylvania. Congratulations!
