Five things you may or may not already know:
Jaws opened on 409 screens on its first weekend in 1975, which was considered a huge number for what was then a "wide" release. Blockbusters often open on 10 times that number now.
If the Earth were reduced to the size of a billiard ball, it would be just as smooth as what you'd find on a pool table. (How's that, you wonder, given we have Everest and ocean troughs? Read here.)

Seaweed has been used to make everything from medical products to food; Toyota is hoping now to develop a car.
