There’s only one kind of magic that I believe in, and it’s this:
Take one cord – USB, ethernet, power cable, doesn’t matter. Straighten it out, and lay it on the ground.
Take another cable – same kind, different kind, longer, shorter, doesn’t matter – and straighten it out, and lay it on the ground next to the first cable.
Look away for a moment, and then reach down to pick up the first cable.
…and it will be tangled up with the second cable already. What the!!!
Everything else has a reasonable scientific explanation. Yes, everything.
Also? I hate cables.
