Every year, the Christmas lights get out away in the box, neatly. You wrapped them the way you were taught by previous generations. But every year, they come out knotted…yet again!!!!
So why does this happen? According to physicists Dorian Raymer and Douglas Smith, then at the University of California, San Diego, the answers is actually scientific.
Yep, science is involved.
- The longer the strand the more likely it is to have a knot…or multiple knots. (BTW, you get fewer knots if the strand is under 18 inches)
- The metal inside the cord is naturally curved. You think that would be a benefit, but it isn’t.
- The rubber or plastic that covers the metal and the wrapped metal expands and contacts to temperatures. So no matter how hard you try, it will end up bending the metal inside.
- Oh and that plastic/rubber coating makes it more likely to get a knot because it is flexible…it is designed to move, so it wants to do it, without human interaction.
- Just so you feel so much better that you will anticipate where the knots will happen next year by putting a colored tape on this year’s culprit…don’t bother. No two knots are the same, nor will the happen in the same place consecutively.
- Then there are the bulbs. Yes, they protrude, so when the box your placed your neatly wrapped cord in gets moved, the bulbs get bumped and lo-and-behold, the cords get jostled. Couple that problem with temperature differences throughout the year, you end up with a perpetual Christmas mess by next year.
Matter of Fact made a nice succinct video to explain better than my opinionated ramblings. (as I am getting mad thinking about next year’s cluster ****)
