[[A woman is standing on the left edge of a rubber sheet. In the middle is a bowling ball. A man in a beret is standing on top of the bowling ball.]]
Beret guy: Imagine a giant bowling ball on a rubber sheet. The ball's weight makes a dent in the sheet.
[[A rope has been attached to the sheet, and is pulling downwards. The woman peers down.]]
Beret guy: Now imagine a rope that pulls the ball down even further. ...Annnnd...
[[The rope snaps. The woman loses her balance as the sheet shakes and the ball flies into the air.]]
BOOOIING
Beret guy: Wheee
[[The woman stands on the now stable sheet. The ball falls down towards it.]]
Woman: ... Oh. I thought this was about physics.
Beret guy: Imagining is fun!
