An application of the Theorema Egregium is seen in a common pizza-eating strategy: A slice of pizza can be seen as a surface with constant Gaussian curvature 0. Gently bending a slice must then roughly maintain this curvature (assuming the bend is roughly a local isometry). If one bends a slice horizontally along a radius, non-zero principal curvatures are created along the bend, dictating that the other principal curvature at these points must be zero. This creates rigidity in the direction perpendicular to the fold, an attribute desirable when eating pizza (since it prevents the pizza toppings from falling off).

Did you just buy a soda in a bottle, opened it and it leaked through the top? There is a way to prevent spilling so that mop of yours [or the store's] doesn't need to be taken out because of soda spills. Here's how:

1. When you first buy a 20-ounce soda [any soda in a bottle, not as effective on cans], don't open it right away.
2. When you want to take a drink, open the lid just enough that you can hear the pressurized gases escape but don't continue.
3. If you see the bubbles rise up rapidly, quickly close the lid. This prevents the bubbles from rising up any more.
4. Once the bubbles go back down, open it again and check. Continue this until the bubbles don't go up any more [which shouldn't be any more than 3 rounds of this].
5. If the bubbles remain down, then open it completely and have your drink.
