Fun fact from a local: The beach that Tom does his monologue from is colloquially known as "Sandy Cove". As far as anyone knows there has never been sand on this beach.
-
Tom Scott could literally talk about anything and entertain me for like, five hours.
-
The expert sounds like the guy they don't listen to in a monster movie.

Hey Tom, son of the owner of the boat featured at 3:51 here. My family was over the moon to see their boat in the video, just letting you know to keep up the good work and if you’re in the area again we can help you with filming or just a pleasure trip!
-
One fact I couldn't fit into the video: the Newlyn Datum doesn't change over time. It's based on a brass marker on that harbour wall. Which means that as the actual sea levels rise, the Sea Level won't. [Edit: and I misspelled geodesy as "geodisy"! Apologies to Prof. Clarke.]

Arthur Dent: "If this is Cornwall, there's something very odd about it" Ford Prefect: "You mean the way the sea stays steady as a rock and the buildings keep washing up and down?"
-
I love how the next recommended video is "Why You Can't Trust Me" , As if Tom's past self does not want to believe this either.
-
Wait Scott went to where I live? Shame I didnt get to see that iconic red shirt bumbling around my area.
-
"a vertical well" that's a good way to build it
-
Another thought on why this doesn't result in constant earthquakes: the sun, moon, and earth have been spinning around one another for billions of years, or so I'm told. If the tidal flexing of Cornwall made the island snap and crack and caused lots of destruction, that would have happened long ago, until eventually it settled down into a state that was flexible enough to just go with the flow, because that's more energetically favorable.
-
I imagine that would cause a bit of a headache for surveyors, whose elevation measurements often have to be accurate to within a couple centimeters or less.
-
Have you ever read something and not believed it? Yeah, that 'Professor of Physical Geo Dizzy' is a real job
-
Me: I don’t care about British tides Tom: Yes you do
-
Alternate title of this video: "THE DAILY UPS AND DOWNS OF LIVING IN CORNWALL" 😊😊😊😊
-
Love how you actually talked of my field of knowledge and i can confirm that you did a well done research :D
-
As a Cornish lad, I did not know this one. Top notch!
-
I find the decibel metres that Tom puts at the side of guest callers quite distracting. It flickers around a bit too much imo. Super interesting video as always though!
-
Binging tom scott videos is so far, THE MOST ENTERTAINING THING for some reason
-
Being from Cornwall, its great to see it being featured on your page, Tom! And for you to be teaching me something I didn't know about the place I live in is brilliant
-
Thanks Tom for being you, and doing your thing.
