But I think at some point we will do something on the very weird nature of quantum and the strangeness that happens when it comes to rotating objects.

Because actually, I mean, there is quite a nice little puzzle, I guess, that we could set people between now and when we do a full episode on this, Michael, right?

Go on, you do it.

You start off with your palm facing down and your hand flat.

And you need to get your thumb pointing in the air without rotating your wrist.

The one that I always remember is that a teaspoon of a neutron star weighs more than the Titanic.

That's insane.

I mean, less than a grain of sugar as opposed to a whole sugar cube.

Amazing.

Basically, not only do you have spin of one, Michael, you're also a whole lot of nothing.

I'm glad for that too.

It does make you think though, you know, sort of, it seems a bit of a shame that things are kind of fixed to the size they were.

Because if you just had like a tiny bit more empty space or a tiny bit less empty space, you could at will change the size of your body from like a three foot tall human, you know, and sometimes I think it would be quite useful to be like poly pocket sized.

Yeah.

And you wouldn't be anywhere near the density of a neutron star for your poly pocket size.

Oh, no.

But it means you could go on a long haul flight, get the cheapest possible seat, and it would be like living in a luxury villa.

Yeah.

Petition for scientists to start working on that immediately.

I think that's where I'm at.
