Teaching the dwarf planets could be fun, though. What about thebfact that Pluto and Charon orbit one another, and how you could build a space elevator directly from.the surface of one to.the other?
wait what? how would that be possible
Pluto and Charon are mutually tidally locked, so they don't rotate in relation to each other.
Plus, in smaller bodies you don't need impossibly strong materials to make a space elevator like you'd need for Earth. Hell, Kevlar fiber is strong enough to make a space elevator from the Moon to one of the Lunar Lagrange points due to the reduced gravity
Space is really huge and it might be possible that the theoretical space elevator would never strike another celestial body.
This is 100% speculative and I have absolutely not done any fact checking other than the fact that space is indeed, really Big McLargeHuge.

They're apparently tidally-locked, so that's one issue out of the way.

So it's pretty close to a circular orbit.
But it'd still have to change length by about 6 km every 3 Earth days.
Maybe this is crazy, but make it a giant jumprope. When they're closer together, the jumprope makes a tighter circle and spins faster. When they're further apart, the jumprope makes a larger circle. Put a weight in the middle so it has enough centripetal force to keep the rope taut.
Trust me, it works, I thought about it for two minutes.
Gotta think that's less (ratio wise) than expansion joints in bridges.
If humanity ever were to have the means to build a 12.2k mile or 19.7k km elevator in space between two planets at the far reach of the solar system, I would assume that we would also be capable of somehow making it longer
It's too late, I'm already going up.
