What about convection? There's been at least some mixing, right? So I'd guess the average age of a nucleus from the core (ignoring fusion) would indeed be less than from the surface, but I would think it's less difference (on average) than the raw math. If there's enough mixing it could be very little difference at all.
Did you end up using adhesive or suction cups or something?
... That's actually possible that it made your friend^2^ understand 3D. They would have manually turned the movie into a Wigglegram and I've read of people who finally 'got it' after seeing those.

Here it is just outright spoiling a joke (censored, but you can see that it quotes the punchline):

Epic win! Lol!
All your base are belong to us.
Ceiling cat is watching
Etc, etc.
Generally explosions do in fact involve an object suddenly increasing in volume (with corresponding decrease in density)
Said objects typically become partially gaseous, but if the rest of it is porous then it's not unusual at all for that to increase in volume also.
Easy example: popcorn.
Assuming it's a surprise, this is Earth All Along. Genre Shift is similar, but that's more about tone than plot
Another prominent example is Android. Sure system apps can be upgraded individually -- by storing the new version in a restricted part of the 'user' partition -- but otherwise the system files are strictly read only until a new 'image' is 'flashed' to it by the update system or a power user with debugging tools. In the past, a common use of root capabilities was to remount the system partition as read/write and then change files on it directly. It's more complex now.
That's also why system apps can be rolled back to the stock version, and can sometimes be disabled, but can't be directly uninstalled like user apps. Only the updated version on the user partition (if there is one) can be removed.
So now we can have an Android port of the "I am rich" app.
Yes it is, and because of who owns it, I would even prefer that to an unsandboxed closed source native binary.
NewPipe at least already doesn't use the API, it scrapes the website.
... Which it just occurred to me might be one of the reasons Google is pushing that web integrity thing. Dang.

Perhaps fanatic.
