Valentines Day in Physics Lab

Bernoulli's Principle: In a fluid, velocity is inversely proportional to pressure.

Scene: Two ping-pong balls, suspended by string at the same height, just a centimeter from each other.
Enter: The Breath.

The Breath blows steadily between the ping-pong balls, causing an increase in velocity and a drop in pressure. The ping-pong balls bump together.

Ms. Jessica asks, What happened?

"They came together." "...and went away to the movies!"
"They're smooching!"

Watch out for those scandalous ping-pong balls.

Science is so risqué...

[Happy Valentine's Day! May your ping find your pong.]

This woman has nothing to do with this post,
but she looks like one cool cat.
