“The earth makes a full rotation in about 23 hours and 56 minutes, not 24 hours. But during that rotation, it’s also revolved 1/365th of the way around the Sun, so it takes about another 4 minutes of spinning before every individual point on Earth gets back to the same (approximate) angle it was at 24 hours ago relative to the Sun (approximate because there’s also axial tilt which causes seasons).”

“Most mammals have penis bones (baculum). Humans are one of the few exceptions.”

“When you take a shot of alcohol it actually activates the receptors in your body to indicate your body is on fire/exposed to heat, which is why alcohol burns on the way down.”

“Some Komodo dragons can reproduce through parthenogenesis (a.k.a immaculate conception)”

“Female ducks evolved to have threaded vaginas because male ducks are considerably rapey. So male ducks evolved to have corkscrew shaped penises so they can carry on fucking. Dirty bastards.”

“Squirrels can survive falling from terminal velocity.”

“If you bleed more than 100ml/min on the international space station, they write you off and say any medical supplies spent on you is a waste.”

“If you ever get a cut and it won’t seem to stop bleeding chances are you’re low on vitamin K as it’s the one that helps your blood clot. Vitamin K can be found in most vegetables”

“Muscles can only contract. Muscle tissue can’t push. Doesn’t sound like a big deal until you realize that actions like sticking your tongue out of your mouth are completely the result of pulling, not pushing.”

“Wombats shit in squares.”

“Koalas have smooth brains and thick skulls that function as helmets cause they fall off trees a lot…why aren’t they extinct yet?”

“-40° is the same whether it’s Celsius or Fahrenheit”

“The sun rises on the ISS every ~90 minutes which is the time it takes to orbit the earth and so astronauts experience about 16 morning every day.”

“When you cry really hard, your nose runs because it’s connected to the same pipes as your tear ducts, so your nose is also helping you get your tears out.”

“Diamonds aren’t forever. In fact, the are dust at 500 degrees in your oven for a few hours. Diamonds aren’t pressure/temperature stable at the surface. If you heat them without also applying incredible pressure, they become CO2 and a little pile of carbon.”

“The enormous pressures in the depths of the ocean have nothing to do with how wide the ocean is. It is simply depth. In other words you can manufacture a steel straw, the width of a drinking straw, make it one mile long, then fill the straw with water to the top: You will have 2,285 pounds of pressure at the bottom of that straw…”

“You’re closer to space than you are to anything more than about an hour’s drive away.”

“Crocodilians are more closely related to birds than they are to other reptiles.”

“Time is slightly slower between higher altitudes and lower altitudes, to infinitesimal fractions of a second.”

“Tyrannosaurus was closer in time to Humans than to Stegosaurus.”
