Do Loose Lips Really Sink Ships?

In the wake of whistleblower Edward Snowden’s leaks about the NSA’s PRISM surveillance program, I keep hearing people roll out the old World War Two phrase “loose lips sink ships.” How literally, I wonder, are we supposed to take that? Have intelligence leaks ever led directly to the loss of a U.S. naval vessel before?

Maybe. Over the course of our naval history, there have been security breaches. At the same time, there have been ships and boats and lives lost. Most of the time, it’s very hard to draw a straight line from an instance of the former to one of the latter. There’s often correlation, but not clear causation. In one of these cases, the lips that might have sunk the ships were attached to a congressman.

During WWII, concerns about national security were probably higher than ever before in U.S. history, and secrecy was paramount to security and the war effort. Civilians were reminded of this through the “loose lips” posters, and many soldiers serving overseas were issued pamphlets that reminded them that…

Silence means security — If violation of protective measures is serious within written communications it is disastrous in conversations. Protect your conversation as you do your letters, and be even more careful. A harmful letter can be nullified by censorship; loose talk is direct delivery to the enemy.

If you come home during war your lips must remain sealed and your written hand must be guided by self-imposed censorship. This takes guts. Have you got them or do you want your buddies and your country to pay the price for your showing off? You've faced the battle front; it’s little enough to ask you to face this "home front."

If only someone had given a copy of that to Andrew J. May. The Kentucky democrat served in the House of Representatives from 1931 to 1947 and chaired the House Military Affairs Committee during the war. During the summer of 1943, May and other House members visited sites in the Pacific Theater and received briefings on operations and intelligence. Upon his return home, May gave a press conference and shared a little too much of what he learned.

Americans didn’t have to worry about the safety of their submarines, he explained, because the Navy had found that the Japanese were setting their depth charges—a type of anti-submarine explosive—to detonate at shallow enough depths that the subs could avoid them. May’s comments were reprinted in various newspapers, including ones in Hawaii and other Pacific coastal areas where subs were operating.

Vice Admiral Charles Lockwood, commander of the U.S. submarine fleet in the Pacific, blamed May’s leak for leading to improved Japanese tactics and American casualties. “I hear Congressman May said the [Japanese] depth charges are not set deep enough,” Lockwood wrote in a letter to another officer. “He would be pleased to know [they] set 'em deeper now." Lockwood estimated that May’s “indiscretion” directly led to the loss of ten subs and 800 seamen.

Lockwood’s accusations and estimates might not be water-tight, though. The Navy’s “Enemy Anti-Submarine Measures” report, a summary of the Pacific fleet’s experience with Japanese anti-sub weapons, makes no mention of a change in depth charge deployment after May’s leak, and says that the Japanese were never able to figure out the full depth capabilities of American subs. Even if the depth charges were set lower, the Japanese still didn’t know how low they had to go before the subs couldn’t maneuver below them. The Naval History Division’s report of submarine losses in the war, meanwhile, does mention the use of depth charges in the attacks leading to the loss of ten subs, but the reports also couldn’t conclude the exact reasons for the loss of each of those subs. The events surrounding some losses were only learned years after the war from enemy reports or other second-hand information, and may not be entirely accurate or definitive.

Representative May, meanwhile, suffered no consequences for his big mouth except some bad press. He was later caught up in scandal, though, and convicted of accepting bribes and using his position to secure contracts and favors for a munitions company. He served nine months in prison and was pardoned by President Truman, but his political career was sunk.

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.”

How Are Rooms Cleaned at an Ice Hotel?

Cleaning rooms at Sweden’s famous ICEHOTEL is arguably less involved than your typical hotel. The bed, for example, does not have traditional sheets. Instead, it’s essentially an air mattress topped with reindeer fur, which sits on top of a custom-made wooden palette that has a minimum of 60 centimeters of airspace below. On top of those reindeer hides is a sleeping bag, and inside that sleeping bag is a sleep sack. And while it’s always 20ºF inside the room, once guests wrap themselves up for the night, it can get cozy.

And, if they’re wearing too many layers, it can get quite sweaty, too.

“The sleep sack gets washed every day, I promise you that. I know it for a fact because I love to walk behind the laundry, because it’s so warm back there," James McClean, one of the few Americans—if not the only—who have worked at Sweden's ICEHOTEL, tells Mental Floss. (He worked on the construction and maintenance crew for several years.)

There isn’t much else to clean in most guest rooms. The bathrooms and showers are elsewhere in the hotel, and most guests only spend their sleeping hours in the space. But there is the occasional accident—like other hotels, some bodily fluids end up where they shouldn’t be. People puke or get too lazy to walk to the communal restrooms. Unlike other hotels, these bodily fluids, well, they freeze.

“You can only imagine the types of bodily fluids that get, I guess, excreted … or expelled … or purged onto the walls,” McClean says. “At least once a week there’s a yellow stain or a spilled glass of wine or cranberry juice … and it’s not what you want to see splattered everywhere.” Housekeeping fixes these unsightly splotches with an ice pick and shovel, re-patching it with fresh snow from outside.

Every room has a 4-inch vent drilled into the icy wall, which helps prevent CO2 from escalating to harmful levels. Maintenance checks the holes daily to ensure these vents are not plugged with snow. Their tool of choice for clearing the pathway is, according to McClean, “basically a toilet brush on a stick.”

When maintenance isn’t busy unstuffing snow from that vent hole, they’re busy piping snow through it. Every couple days, the floor of each room receives a new coat of fluffy snow, which is piped through the vent and leveled with a garden rake.

“It’s the equivalent of vacuuming the carpet,” McClean says.
