How Did Nickelodeon Make Green Slime?

Nickelodeon’s iconic slime made its first appearance on You Can't Do That on Television, the Canadian-made sketch comedy show that ran from 1979 to 1990. From there, it became a staple of almost everything the network did, with regular slimings on many programs, at the Kids' Choice Awards and at the Nickelodeon Studios attraction at Universal Studios Florida.

According to Bill Buchanan, a crew member on You Can't Do That on Television for its whole run, the slime was invented early in the show’s history. He was working in the props department one weekend when he got a rundown of items needed for an upcoming show. One of the sketches called for “this kinda disgusting slimy green stuff,” but there were no further details, or even an indication of how the stuff would be used.

Another propmaster, Paul Copping, was given the task of making the slime, and even after asking the director and the scriptwriter, he couldn’t get any more details on what the slime was suppose to be. So, he just went with his gut and mixed up a whole garbage can full of slime. Buchanan says he knows the color came from green latex paint, but didn’t know what else was in it. It smelled and looked foul. People avoided the can while walking through the studio. Bits of sausage may have been floating in it.

The day the slime scene was shot, the propmasters learned the slime’s purpose. It was supposed to be dumped on one of the actors. There was an argument. The producers wanted to go ahead and do the scene, but the prop guys were worried there was something in there that could hurt the actor or make them sick. The sketch got pulled until a new slime could be made. While the old stuff stayed in the garbage can and festered in a corner of the studio, Buchanan, Copping and company got started on a new formula that could get in someone’s eyes and mouth without causing any problems.

This second batch was made mostly from green Jell-O that had been set in the fridge, then pulled out the day before shooting to liquefy and get mixed with flour.

That slime recipe was used for a while, but it required too much preparation time. If the crew had to have the slime ready earlier than expected, it wasn’t fluid enough and had solid chunks of Jell-O in it. They needed a way to make lots of slime on short notice, and turned to Quaker Oats Crème of Wheat for the next generation of slime. They’d basically stir the cereal up cold on the spot in whatever amount they needed, and then dump in green food coloring. The problem with that recipe was that it turned pasty as it dried, and the actors found they couldn’t get it out of their hair. They countered that problem by adding a couple of drops of baby shampoo to the mixture, and stopping tape after a sliming so the actors could rush off the set and into the showers before the slime hardened.

Slime evolved for other shows over the years. Cottage cheese and vegetable oil are sometimes mentioned as ingredients. As Double Dare host Marc Summers explained, most of the slime used on his shows was made of “vanilla pudding, applesauce, oatmeal, green food coloring, and by the third day, anything else that was on the obstacle course.” Yum.

What Makes a Cat's Tail Puff Up When It's Scared?

Cats wear their emotions on their tails, not their sleeves. They tap their fluffy rear appendages during relaxing naps, thrash them while tense, and hold them stiff and aloft when they’re feeling aggressive, among other behaviors. And in some scary situations (like, say, being surprised by a cucumber), a cat’s tail will actually expand, puffing up to nearly twice its volume as its owner hisses, arches its back, and flattens its ears. What does a super-sized tail signify, and how does it occur naturally without help from hairspray?

Cats with puffed tails are “basically trying to make themselves look as big as possible, and that’s because they detect a threat in the environment," Dr. Mikel Delgado, a certified cat behavior consultant who studied animal behavior and human-pet relationships as a PhD student at the University of California, Berkeley, tells Mental Floss. The “threat” in question can be as major as an approaching dog or as minor as an unexpected noise. Even if a cat isn't technically in any real danger, it's still biologically wired to spring to the offensive at a moment’s notice, as it's "not quite at the top of the food chain,” Delgado says. And a big tail is reflexive feline body language for “I’m big and scary, and you wouldn't want to mess with me,” she adds.

A cat’s tail puffs when muscles in its skin (where the hair base is) contract in response to hormone signals from the stress/fight or flight system, or sympathetic nervous system. Occasionally, the hairs on a cat’s back will also puff up along with the tail. That said, not all cats swell up when a startling situation strikes. “I’ve seen some cats that seem unflappable, and they never get poofed up,” Delgado says. “My cats get puffed up pretty easily.”

In addition to cats, other animals also experience piloerection, as this phenomenon is technically called. For example, “some birds puff up when they're encountering an enemy or a threat,” Delgado says. “I think it is a universal response among animals to try to get themselves out of a [potentially dangerous] situation. Really, the idea is that you don't have to fight because if you fight, you might lose an ear or you might get an injury that could be fatal. For most animals, they’re trying to figure out how to scare another animal off without actually going fisticuffs.” In other words, hiss softly, but carry a big tail.

What Happened to the Physical Copy of the 'I Have a Dream' Speech?

On August 28, 1963, Martin Luther King Jr. stood on the steps of the Lincoln Memorial and gave a speech for the ages, delivering the oratorical masterpiece "I Have a Dream" to nearly 250,000 people.

When he was done, King stepped away from the podium, folded his speech, and found himself standing in front of George Raveling, a former Villanova basketball player who, along with his friend Warren Wilson, had been asked to provide extra security around Dr. King while he was speaking. "We were both tall, gangly guys," Raveling told TIME in 2003. "We didn't know what we were doing but we certainly made for a good appearance."

Moved by the speech, Raveling saw the folded papers in King’s hands and asked if he could have them. King gave the young volunteer the speech without hesitation, and that was that.

“At no time do I remember thinking, ‘Wow, we got this historic document,’” Raveling told Sports Illustrated in 2015. Not realizing he was holding what would become an important piece of history in his hands, Raveling went home and stuck the three sheets of paper into a Harry Truman biography for safekeeping. They sat there for nearly two decades while Raveling developed an impressive career coaching NCAA men’s basketball.

In 1984, he had recently taken over as the head coach at the University of Iowa and was chatting with Bob Denney of the Cedar Rapids Gazette when Denney brought up the March on Washington. That's when Raveling dropped the bomb: “You know, I’ve got a copy of that speech," he said, and dug it out of the Truman book. After writing an article about Raveling's connection, the reporter had the speech professionally framed for the coach.

Though he displayed the framed speech in his house for a few years, Raveling began to realize the value of the piece and moved it to a bank vault in Los Angeles. Though he has received offers for King’s speech—one collector wanted to purchase the speech for $3 million in 2014—Raveling has turned them all down. He has been in talks with various museums and universities and hopes to put the speech on display in the future, but for now, he cherishes having it in his possession.

“That to me is something I’ll always be able to look back and say I was there,” Raveling said in the original Cedar Rapids Gazette article. “And not only out there in that arena of people, but to be within touching distance of him. That’s like when you’re 80 or 90 years old you can look back and say ‘I was in touching distance of Abraham Lincoln when he made the Gettysburg Address.’"

“I have no idea why I even asked him for the speech,” Raveling, now CEO of Coaching for Success, has said. “But I’m sure glad that I did.”
