Sundials designed for the North won't work in the Southern Hemisphere. If ported there, they would reckon time backwards. — PolitiTweet.org

Some of us in the North are jealous that 100% of the world’s population of free Penguins live in the Southern Hemisphere. — PolitiTweet.org

Earth is not only oblate — wider at the equator than pole-to-pole, but pear shaped — slightly wider just south of the equator — PolitiTweet.org

Earth's centrifugal force at the Equator renders everybody and everything about 6% lighter than they’d weigh at the poles. — PolitiTweet.org

I think it's cool that there's a country on the equator with the name "Equator". Better known in Spanish as Ecuador — PolitiTweet.org

The flag in Antarctica that ID's the South Pole has to be repositioned every year. The glacier beneath moves continuously. — PolitiTweet.org

The South Pole is covered with land: Antarctica. In the North, Santa’s gotta live on an (ever-shrinking) slab of floating ice — PolitiTweet.org

At about 2800 meters above sea level, the South Pole plateau sits at an elevation almost as high as that of Mount Olympus. — PolitiTweet.org

Toilet Bowls drain however they're designed to circulate water. It’s irrelevant whether you live above or below the equator. — PolitiTweet.org

Asteroid “70713 @SethMacFarlane” orbits the Sun between Mars & Jupiter. I double checked: no chance of it hitting Earth. — PolitiTweet.org

When Queen Elizabeth succeeded King George in 1952, I wonder why the United Kingdom wasn't renamed the United Queendom. — PolitiTweet.org
