00:00The mystery of spaghetti that always snaps into three pieces, a puzzle that even a genius
00:04physicist couldn't crack. Snapping a strand of spaghetti into just two pieces by bending it
00:09from both ends is, in theory, nearly impossible. Even Richard Feynman, a Nobel Prize winning
00:14theoretical physicist, was stumped by this problem and never found the answer. For nearly 40 years
00:19after that, researchers around the world took on the challenge, yet no one could explain it.
00:23Then, a team of French researchers finally cracked the mystery. When spaghetti snaps,
00:28the shockwave travels through the strand like a ripple, and that wave, known as the snapback
00:32effect, triggers a chain reaction that breaks the pasta in yet another spot. Years later, MIT students
00:38made another breakthrough. By twisting the spaghetti 270 degrees while bending it, they found that the
00:43shockwave is cancelled out, and the strand snaps cleanly into just two pieces. Today, this discovery
00:48has been applied to real-world engineering, helping predict how structures like bridges and buildings
00:52will fracture and collapse.
