Is it worth closing the lid on a toilet before flushing? (lemmyrs.org)

This seems like something that should be true, but I think I remember seeing a Mythbusters episode where they decided it didn't make a difference. That show was more about entertainment than science, so I wondered if there was a more rigorous study done? I've definitely seen splashes of water(?) come out from flushes so that alone seems to argue for closing lids.

Why are coils so good at dispersing energy? (mander.xyz)

For example, there is a cable from my monitor to my desktop that when plugged in straight is able to be disturbed or dislodged from my dog walking past it and the hairs on the top of his tail touch it with micronewtons of force. Yet if I coil it just 3 turns over 3 feet length it can withstand 10000 times as much force before becoming loose.

Another thing I'm reminded of is the coils in phone cords back when everything was wired with handsets. This must be a well known principal but I don't ever remember learning it.
