The correct answer is: Heavier weights increased the knot failure rate.
"Science: WhyShoelace KnotFailure"
by Nsikan Akpan
The team built a robotic pendulum to examine themath on a deeper level. They found the knot’s failureintensifies overtime. As the length of the loose endincreases, so too does its weight relative to the otherstrand. This trend adds to the inertial forces, untiltotal shoelace failure. Moreover, the bows of yourshoelace are not exempt for this flaw.
“Some people will have very long free ends relativeto the bow, in that case, the free ends will go firstand the bow will just vanish,” O’Reilly said. “The bowcan increase in size, and the free ends will vanish.”
When the team added little weights — ranging from1 to 3 grams — to the free ends of the laces, theyfound heavier weights caused the shoelace knots tofail at a higher rate. This result suggests laces madefrom heavier materials may be more prone toscrewing up, because unless you’re phenomenallygifted at tying even knots, one free end will likely belonger than the other.
Though the amount of time before a failure varied,the researchers argued these basic knots willeventually slack off. Also, you can try tying a tighterknot, but even those may break your heart.
