Several commenters correctly solved yesterday’s puzzle…..
$100,000 in hundred dollar bills weighs about two pounds on earth. So does a cubic yard of air.
On earth, when you weigh a lockbox full of air on a balance scale, you’re weighing just the lockbox, not the air — because there’s an equal amount of air pushing down on the other side.
But on the moon, when you weigh a lockbox full of air on a balance scale, you’re weighing both the lockbox *and* the air (because no air is pushing down on the other side). So the lockbox should balance against two more pounds on the moon (or, to be more precise, if on earth it balances against 100 little weights each weighing a pound, then on the moon it will balance against 102 of those little weights).
Since the lockbox on the moon balances against 100 pounds, instead of the expected 102, two pounds worth of something must have been removed — before Barb ever came into the picture. Unless Al somehow let the air escape from the box, he’s the one who stole your two pounds of money.
Hat tip to a person called jitter.
