|Apparently, a bent dry spaghetti does not break in half but instead in three or more pieces.
After careful experiments, scientists discovered that ".. the mere release of the rod induces a stress increase. The multiple breaking of bent rods, like dry spaghetti pasta, can then be understood as a cascade of releases (loss of cohesion upon breakings) followed by stress increases leading to new cracks"
