A Physicist Weighs In On Whether Scrooge McDuck Could Actually Swim in a Pool of Gold Coins

Batman has the Batcave, Superman has his Fortress of Solitude, and Scrooge McDuck has his money bin. For 70 years, the maternal uncle of Disney’s Donald Duck has been portrayed as a thrifty—some might say miserly—presence in cartoons and comics, a waterfowl who has such deep affection for his fortune that he enjoys diving into his piles of gold and luxuriating in them.

It’s a rather gross display of money worship, but is it practical? Can anyone, including an anthropomorphic Pekin duck, actually swim in their own money, or would diving headfirst into a pile of metal result only in catastrophic injury?

According to James Kakalios, Ph.D., a professor of physics at the University of Minnesota and author of the recently-released The Physics of Everyday Things as well as 2005’s The Physics of Superheroes, the question really isn’t whether someone could swim in a mass of gold. They could not. It’s more a matter of how badly they’ll be injured in the attempt.

Diving into a gold pile the Scrooge way—hands first, prayer-style, followed by your head—is the most efficient way to begin breaking bones. “Keeping his arms stiff and his elbows rigid, he’s definitely going to break his wrists,” Kakalios tells Mental Floss. “Gold is a granular material like sand, a macroscopic object. You can’t swim through sand or dive into it easily.” Launch yourself off a diving board from 3 or 4 feet up and you will meet a solid surface. Landing with your feet, a far better bet, is unlikely to result in injury—provided you try to bend your knees.

In that sense, diving into gold is not dissimilar from “diving” into a concrete floor. But with gold being granular, it might be possible to break the surface and “swim” if the friction were low enough. “A ball pit is a good example,” Kakalios says. “The balls are lightly packed and have low friction relative to one another. The key is to have objects in front of you move out of the way in order to advance.”

Despite being a fictional character, McDuck hasn’t totally ignored the impossible physics of his feat. His creator, Carl Barks, has written in repeated references over the years to the implausibility of using his money vault as a swimming pool and has depicted the villainous Beagle Boys trio as getting hurt when they tried to emulate the stunt. Scrooge smirked and said there was a “trick” to making the gold dive.

That’s led to one fan theory that McDuck has used his fortune to coat the gold coins in some kind of lubricant that would aid in reducing friction, allowing him to maneuver inside the vault. Ludicrous, yes. But is it possible? “You would need a massive amount of lube to slide your body past the coins with minimal effort,” Kakalios says. “The ball pit is easier because the weight of the elements is low. Gold is a very dense material.” Diving and swimming into it, even with lubricant, might be analogous to trying to shove your hand into a deep bowl of M&Ms, he says. “M&Ms have a low friction coating. Continuing to move is really the problem.”

Presuming McDuck could somehow maneuver himself deeper into the pile, his delicate duck bones would almost surely succumb to the crushing weight of the gold above him. By one estimate, diving under one of his 5-foot-tall gold piles would put 2492 pounds of pressure on his bill.

We'll see if he tips his top hat to any further gold-diving tricks—or if he's in a full-body cast—when Disney XD relaunches DuckTales this summer.

It's True: Men's Pockets Really Are Deeper Than Women's

Your phone peeks halfway out of the pocket of your jeans.

Your pocket-sized wallet is too large to fit.

You go to tuck a dollar into the pocket of your new dress pants, only to find that the opening is sewn shut.

If these scenarios sound familiar, you’re probably a woman. As Lifehacker reports, an investigation into 20 popular clothing brands revealed that the pockets on women’s pants really are shallower and narrower than men’s. About half as deep, in fact.

These findings come from The Pudding’s team of journalist-engineers, who produced a visual essay (with interactive infographics!) on the sartorial subject.

The announcement probably won’t surprise women, but for the sake of closing the pocket gap once and for all, the statistics are still worth noting: Women’s jeans pockets are 48 percent shorter and 6.5 percent narrower than men’s.

Furthermore, only 40 percent of front pockets can fit a smartphone—the iPhone X, Samsung Galaxy, and Google Pixel were all put to the test. The same statistic applies to wallets that were specifically designed to fit inside a front pocket. And two percent of women’s pockets can’t even hold a pen (compared to zero percent of men’s pockets).

Remember that time Alanis Morissette sang, “I’ve got one hand in my pocket?” As it turns out, only 10 percent of women can relate to this lyric—the same percentage of women who can actually fit their hand inside their front pocket.

As The Pudding points out, this isn’t just a matter of differences between men’s and women’s sizes, either. “Here we measured 80 pairs of jeans that all boasted a 32 inch waistband, meaning that these jeans were all made to fit the same size person,” The Pudding says.

So what’s going on? Some sources have suggested that the fashion industry is inherently sexist, favoring design over function. "I don't feel like they're taking women seriously as a market," Julie Sygiel, founder of The Pockets Project, told The Week. Sygiel plans to create a line of dresses with pockets that are least 8.5 inches deep.

While this pocketless trend is rooted in history—women started wearing hip purses in the 18th century to compensate for the lack of internal pockets—many women are hoping that the 21st century will be the dawn of a new era for functional fashion.
