    If presented with an old 1970-2000 era landline phone, I can call someone by rapidly hanging up in the pattern of their phone number.

      Used to do those in payphones as a kid. The numbers were disabled when no coins were inserted, effectively disabling tone dialing impossible. But pulse dialing still worked.

      I am pretty sure I could do it sans phone and only the handle, by rapidly pulling the plug out of the socket and putting it back in.

      Never thought to try it when I had the chance.

      In case anyone is wondering, this is how old phones with rotary dials worked: you wound the dial to the digit you needed and the built-in mechanism would automatically wind it back; as it did it would momentarily disconnect the line as it passed each digit generating pulses that the exchange would count. If you still live somewhere where landline phones exist odds are this still works because the exchange maintains backwards compatibility with pulse dialling.

      Up until about twenty years ago virtually every supermarket had a phone by the checkouts with a single pre-programmed button for a local taxi company; we used this trick all the time to call home, our mates, etc.

    The “brat” in “bratwurst” doesn’t come from “braten”, which means to fry. It actually comes from the old German word “brät”, which means finely chopped meat.

      I’m convinced people that “can’t” just don’t know how.

      It’s the same movement as closing your throat off so you can open your mouth underwater, and you just push “up” past that till it puts pressure on the eustachian tubes, and the rumble is your muscle fibers contracting against that which resonates on your eardrums.

      Anyone can do it, it’s just hard to explain

        That’s a minor sound when I do it if I understand correctly. Audible but light. I can flex the muscles in my jaw/tongue as one would to attempt to pop ears, but pushing out from the back of the mouth and pulling my jaw backwards. I think it slightly restricts blood flow and makes it turbulent past the ear. Sounds like pulsar tinnitus (probably not relatable) but constant as long as I hold it.

          Yeah, that’s it.

          I think some people just do the “water lock” thing to close their jaw off naturally to try and stop a yawn, and that’s how they “discover” they can do it.

        Ooh, I can make a little rumble thunder happen if I do that! But why would anyone want to? And weirdly, just yawning doesn’t really do it, but squeezing the eyes while yawning does. Huh.

    **Grostesques ** are mythical or fantastical creatures carved into the sides of building. If they have been designed to drain water away from the building, they are called gargoyles .

    An electric eel is not an eel.
    A mountain goat is not a goat.
    A maned wolf is not a wolf.
    A mountain chicken is not a chicken.

    Also, there is an animal called the Headless Chicken Fish.

    None, because knowledge and the search for it is an end unto itself, so all facts are useful to learn and know.

    There are several rivers in England called the Derwent.

    One of them flows into the Ouse in Yorkshire, another flows into the Trent in Derbyshire, both of which later combine to form the Humber estuary, so the Humber has two Derwents in it

      Forza Horizon 4 has an awesome open map based on several disparate areas of England and Scotland pushed together. It includes the Derwent Reservoir and damn, which drains into one of the Rivers Derwent, which leads to Derwent Water - none of which are actually connected in real life. I thought that was a neat Easter Egg.

    The synths that were used in the first doom reboot’s music were made from samples of an actual chainsaw running.

      Are you this person who, at the family gathering, will loudly decline words in a long dead language they forced you to learn 50 years ago, just to call it useful?
