Is there a law .....?
I was in a scavenger hunt once and one of the objects was a foreign coin.
I knew my mom had one, but it was my partner's turn to retrieve the object, while I drove.
We were in his car, a somewhat vintage mercedes being restored and without carpet...don't know why but he decided to throw the coin while I changed sides to be the passenger. It went between my hands and into the car. I watched it hit the floor board on top of a "hat shaped" unibody brace, and slide down the length perfectly parallel (despite the odd angle it struck at) until it found a hole that was exactly 1/32" larger than the coin, fall in and continue sliding.
It took 35 minutes, a coat hanger, a ball of tape, and a pair of tweezers to retrieve that coin.
We came in second.
Interestingly the first item was prize from a claw machine.
I got it on the first try after never having been successful on those for my entire life.
