Bill Nye the Science Guy

"Science rules!"

"We're all just a bunch of bones."

"Get a metal spoon - the bigger and shinier the better. A good soup spoon is best. Look at the back side - the side that won't hold any soup. Your nose is a little big, but you look like you. Now, turn it over so that you're looking at the scoop side. You're upside down? To see why this happens, think of lines of light traveling to the spoon and back to your eye. Since the spoon is curbed, the light hits it at an angle. That means it bounces off at an angle, too. The angle is sharp enough to make the top and bottom cross on the reflected light's way back to your eye."

"Anyway, here's the deal. All animals, including you and me, need oxygen to breathe. Animals breathe in oxygen, breathe out carbon dioxide; plants breathe in carbon dioxide and breathe out oxygen. So even if you're never going to eat my broccoli again, all animals, and that includes you, pal, need plants because we need oxygen to breathe."

"OK, the suit's pressurized, cooling water's flowing, the breathing air is pumped in. If you think about it, it's a spaceship . . . for ONE!"
