How To Behave In Public - Water Fountains

Water is the single most important component for life on Earth. 70% of the human body is made of water. If you place your ear against a person who is jumping up and down, you might even be able to hear some of that water sloshing about. Isn't science fascinating? In order to live, a human must drink at least two gallons of what every day. Fortunately, American scientists armed with this knowledge were able to invent one of the most important devices we have in today's society. 

How To Behave In Public - Elevators

Congratulations! You've discovered vertical transportation through the miracle of the Elevator!! Elevators carry 3.82 billion people over 82.3 quadrillion vertical miles every single day. Elevators are one of the single most popular modes of transportation on the planet. Now that it's the first time you've been in a elevator, you should take a moment to savor that landmark you have achieved. 

The best things in life aren't yellow

It's amazing the number of things that are yellow in color that are unappealing. Lemonade is pretty great, but I wouldn't say it's a best thing in life. It's not even that yellow and it's liquid, so there's no chance of it looking like a banana. There might be a banana-shaped drink pitcher or beer mug, though. Closely related to lemonade, but produced in a completely different manner and lacking lemonade's appeal, is urine. Sure, you can pee into your radiator or write your name (poor penmanship included) in snow or even drink it if you are lost in a desert, but it's not considered a good drink. I doubt chilling it or adding sugar would improve the taste. Then again, some people go gaga over coffee beans that a cat shit out.
