Scientists Discover How to Snap Spaghetti Into Two Perfect Pieces

Important news for pasta lovers: Researchers at MIT just figured out how to snap a strand of spaghetti into two perfect pieces, according to New Scientist. The days of having to sweep up the tiny fragments that fly in all directions when you break spaghetti into two pot-ready portions are over.

In 2005, researchers in France figured out why spaghetti cracks into bits: The strand flexes in the opposite direction after the initial snap, creating a “snap-back effect” that causes it to break a second time.

Now, after snapping hundreds of spaghetti sticks, MIT mathematicians have the solution. The researchers used a pair of clamps to twist individual strands of spaghetti almost 360 degrees. Next, the two clamps were slowly brought together to bend the stick, resulting in a perfect fracture. This worked for two kinds of spaghetti with different thicknesses—Barilla No. 5 and Barilla No. 7, to be precise.

The process was recorded using a high-speed camera (which can be viewed on MIT's website). While reviewing the footage, researchers realized that adding a twist is key because it prevents the spaghetti stick from forcefully flexing backwards. Their findings were published in the Proceedings of the National Academy of Sciences.

Even without equipment, you can can try this at home. It might take a bit of practice, though, so have a couple of boxes handy. Ronald Heisser, a former MIT student who is now a graduate student at Cornell University, came up with the technique for how to manually snap spaghetti in two.

“I would start with my hands opposite each other—one hand upside down and the other right side up—and then make both of them right side up while twisting the spaghetti so you can work your arm strength into it,” Heisser tells Mental Floss.

“You know you're twisting it right when you feel it really trying to untwist itself. Then, you can carefully bring the ends together, trying not to change the twist at all.”

He noted that your hands should also be dry, because oiliness can make the strand slip in your fingers.

However, it's unlikely that anyone has the patience to sit there and snap one strand of spaghetti at a time. So does this trick work for a whole handful of pasta? Dr. Jörn Dunkel, who led the study, says it’s difficult to predict how a handful of spaghetti would fracture, but he believes this technique would reduce the number of pieces you end up with.

“When many spaghetti [strands] become bunched together, they can transfer energy between them, which can change their bending and fracture behavior significantly,” Dr. Dunkel tells Mental Floss. “Very roughly, as a rule of thumb, one would expect that splitting the energy between bending and twisting should always help to reduce the fragment number compared to pure bending.”

Of course, if you want to cook the true Italian way, you’ll leave your spaghetti unsnapped and intact. (Longer pasta is said to wrap around your fork better, making it easier to eat.)

But if you want to try this bend-and-snap technique for yourself, the purists would probably give you a pass.

How the Scientist Who Invented Ibuprofen Accidentally Discovered It Was Great for Hangovers

When British pharmacologist Stewart Adams and his colleague John Nicholson began tinkering with various drug compounds in the 1950s, they were hoping to come up with a cure for rheumatoid arthritis—something with the anti-inflammatory effects of aspirin, but without the risk of allergic reaction or internal bleeding.

Though they never exactly cured rheumatoid arthritis, they did succeed in developing a nonsteroidal anti-inflammatory drug (NSAID) that greatly reduced pain of all kinds. In 1966, they patented their creation, which was first known as 2-(4-isobutylphenyl) propionic acid and later renamed ibuprofen. While originally approved as a prescription drug in the UK, it soon became clear ibuprofen was safer and more effective than other pain relievers. It eventually hit the market as an over-the-counter medication.

During that time, Adams conducted one last impromptu experiment with the drug, which took place far outside the lab and involved only a single participant: himself.

In 1971, Adams arrived in Moscow to speak at a pharmacology conference and spent the night before his scheduled appearance tossing back shots of vodka at a reception with the other attendees. When he awoke the next morning, he was greeted with a hammering headache. So, as Smithsonian.com reports, Adams tossed back 600 milligrams of ibuprofen.

“That was testing the drug in anger, if you like,” Adams told The Telegraph in 2007. “But I hoped it really could work magic.”

As anyone who has ever been in that situation can probably predict, the ibuprofen did work magic on Adams’s hangover. After that, according to The Washington Post, the pharmaceutical company Adams worked for began promoting the drug as a general painkiller, and people started to stumble upon its use as a miracle hangover cure.

“It's funny now,” Adams told The Telegraph. “But over the years so many people have told me that ibuprofen really works for them, and did I know it was so good for hangovers? Of course, I had to admit I did.”
