Just get the pressure off yourself.
Yes.
And understand that will happen and don't try and avoid that thing.
I love this.
Oh yeah.
So here's an example of just a very simple demo.
I'll pull up that's down.
Yes, this is a simple hair dryer you'd have at home and just a ping pong ball.
Yeah, okay.
So what I'm going to do, Mel, I'm going to turn this on.
And the ping pong ball is levitating in this hair dryer.
But even as you twist it left and right, it like magically stays in the airflow, right?
So this is a principle called the Koanda effect.
Essentially what's happening is it's creating like a little low pressure bubble for the ball to float in.
That's why even at a side angle like this, it's still floating.
This is what the principle behind what makes curve balls curve in baseball.
It's like the same kind of principle of like air flowing around the side to create little bubbles.
I'm learning.
It's exactly it, Mel.
Wow, you explained that so well.
