Watch This Slow Motion Video of What Happens When You Gargle

Taking a cue from The Magic School Bus, YouTube sensations The Slow Mo Guys took a break from exploring the way things smash, burn, and explode to scope out a more common phenomenon: gargling. Gavin Free and Daniel Gruchy aimed their camera down Gruchy's throat to see if the act of rinsing the throat and mouth would look more interesting in slow motion. "It will either be really boring or fascinatingly gross," Free predicted. (Spoiler alert: It's the latter.)

The team conducted two trials, one in which Gruchy mimicked the sound of gargling without any liquid and one in which he gargled with water. In both cases, the uvula, which scientists believe aids speech, can be seen thrashing around in slow motion. ("It looks like a second tongue going ape in the back of your mouth," Free notes.)

While it may not be pretty, there are a few reasons why you should consider making it a part of your daily routine. The act of gargling helps break up mucus and remove irritants—such as fungi, bacteria, and allergens—from the throat, according to The New York Times. The simple act can also help lower your chances of picking up an upper respiratory tract infection (URTI): A 2005 study published in The American Journal of Preventive Medicine found that participants who regularly gargled had a 40 percent decrease in URTIs. But it does more than stave off infection; gargling with sugar water has been shown to help people have more self control.

After weeks of mailing out this year’s holiday cards, postage might be the last thing you want to think about. But the U.S. Postal Service has just given us a sneak peek at the many iconic people, places, and things that will be commemorated with their own stamps in 2018, and one in particular has us excited to send out a few birthday cards: Mister Rogers.

In celebration of the 50th anniversary of Mister Rogers’ Neighborhood, Fred Rogers’s groundbreaking PBS series that the USPS says “inspired and educated young viewers with warmth, sensitivity, and honesty,” the mail service shared a mockup of what the final stamp may look like. On it, Rogers—decked out in one of his trademark colorful cardigans (all of which were hand-knitted by his mom, by the way)—smiles for the camera alongside King Friday XIII, ruler of the Neighborhood of Make-Believe.

Though no official release date for Fred’s forever stamp has been given, Mister Rogers is just one of many legendary figures whose visages will grace a piece of postage in 2018. Singer/activist Lena Horne will be the 41st figure to appear as part of the USPS’s Black Heritage series, while former Beatle John Lennon will be the face of the newest Music Icons collection. Sally Ride, the first American woman in space, will also be honored.
