MARY: Are you still squeezing on that toothpaste tube? Give up! It's empty!
KARL: Little-known fact: toothpaste tubes do not contain toothpaste. They CREATE toothpaste.
KARL: When you squeeze the tube, you generate energy. This powers a chemical reaction that results in the formation of a semi-solid mass. Which plops out the end. Theoretically it's unlimited! But because of the half-life of the chemical catalysts, each reaction requires twice as much energy as the one before.
KARL: So the first draw - when the tube seems "full" - requires 0.0001 units of squeezing force. The second, 0.0002 units, etc. It's easy at first, but that doubling gets serious after a while. Eventually it takes TRILLIONS of units of force! QUADRILLIONS!
KARL: Most people give up when it gets too tough. But I've got a vise and a torque wrench.
MARY: JUST GET A NEW TUBE OF TOOTHPASTE
