10 facts maybe you don't know

In Back to the Future, the time machine was originally an old fridge.

When you watch 1985’s Back to the Future, you’ll see that the main character, Marty McFly (Michael J. Fox) travels back to the ’50s in a DeLorean car that’s been turned into a time machine. And while the DeLorean became a signature part of the film, we have to wonder what the movie would have been like if the producers had gone with their original concept, which was to make the time machine an old refrigerator.

According to HuffPost, “Ultimately, it was determined that it probably was not a good idea to use a refrigerator in such a manner as kids might want to re-enact the scene.” Parents everywhere are grateful.

In 2009, renowned theoretical physicist and cosmologist Stephen Hawking decided to throw a party, but none of his guests showed up. However, they weren’t being rude. It turns out that they didn’t receive an invitation for the event until well after the fact—which was the plan… to test time travel.

Hawking explained in 2012 to Ars Technica, “I gave a party for time-travelers, but I didn’t send out the invitations until after the party. I sat there a long time, but no one came.”

Birth control for men exists.

Taking birth control is not just for women. In 2016, scientists announced that they had developed an injectable male contraceptive that was found to be 96 percent effective in the men who used it. Using the hormones progestogen (which affects sperm production) and testosterone (which reduces the effects of the progestogen), the treatment could help equalize the burden of control between the sexes.

World War I boosted the bra market.

During the First World War, the U.S. War Industries Board asked American women to forgo their corsets—which required significant amounts of metal to construct, according to NPR. Instead, they were expected to switch to the less-demanding bra. The ladies did their part for the cause, freeing up to 28,000 tons of metal—enough to build two battleships—and changing female fashion from that moment forward.

Eating pistachios can help reduce erectile dysfunction.

For a 2011 Turkish study published in the International Journal of Impotence Research, 17 men with erectile dysfunction were given 100 grams of pistachios to eat for lunch every day for three weeks. The subjects were then measured on the International Index of Erectile Function—and the pistachios proved to improve blood flow and the dilation of blood vessels. Hey, it’s certainly a cheaper option than Viagra!

Caterpillars turn into soup before becoming butterflies.

We all know that caterpillars create a cocoon in which they transform into beautiful butterflies, but what actually goes on inside that cocoon is pretty gross: The insect actually “digests itself, releasing enzymes to dissolve all of its tissues,” as Scientific American explains. Once it’s fully disintegrated (excluding some “imaginal discs”), it then begins “the rapid cell division required to form the wings, antennae, legs, eyes, genitals, and all the other features of an adult butterfly or moth.”

The Guinness World Records lists Bakken in Klampenborg, Denmark, as the oldest still-operating amusement park in the world. The park, which opened in 1583, features more than 150 attractions, including a wooden roller coaster that was built in 1932.

According to the records book, Bakken wasn’t totally unique in its time. “In medieval Europe, most major cities featured what is the origin of the amusement park: the pleasure gardens,” they write. “These gardens featured live entertainment, fireworks, dancing, games, and some primitive amusement rides.”

Penguins used to be almost seven feet tall.

Researchers from the La Plata Museum in Argentina found fossils in the Antarctic of a “colossus penguin,” measuring six feet, eight inches in height. According to the researchers, the larger penguins would have been able to dive underwater for 40 minutes at a time!

10.Nicolas Cage and Jake Gyllenhaal could’ve been Aragon and Frodo in The Lord of the Rings.

It may be hard to imagine anyone else as Frodo or Aragorn in The Lord of the Rings film franchise, but before Elijah Wood and Viggo Mortensen nabbed the coveted roles, many famous actors were considered. For example, Nicolas Cage was offered the role of Aragorn but turned it down, telling Newsweek, “There were different things going on in my life at the time that precluded me from being able to travel and be away from home for three years.”

And Jake Gyllenhaal might have been Frodo, but he bombed the audition for one not-so-small reason. “I remember auditioning for The Lord of the Rings and going in and not being told that I needed a British accent. I really do remember [director] Peter Jackson saying to me, ‘You know that you have to do this in a British accent?’” he recalled to The Hollywood Reporter. “We heard back it was literally one of the worst auditions.”
