That makes sense. It's good to have the history preserved. These Amentans are not aware of any nations that have been completely wrecked by volcanoes, but now and then a city will have an issue.

Getting completely wrecked by a volcano is really rare. Most volcanic eruptions cause lots of problems but leave enough survivors that they can come back and rebuild once the water's safe again.

And what's going on in this here science museum?

This here science museum has a really fancy exhibit on robotics!

Gosh! Amenta's behind on robotics, because the red caste, recently phased out, was against automation, but they're trying to catch up now and would love to know what the mermaids know.

The mermaids have really really good computer science! The hard part of robots for them is keeping everything waterproofed that needs to be. This museum exhibit is mostly designed for laypeople and mostly contains "the very very basics of how robots work in theory" and "ways in which these robots are more advanced than their predecessors" but the Amentans can totally talk to mermaid roboticists if they want. 

They should set that up with Amentans who know more about the fledgeling field of Amentan robotics than these scuba divers do.

That makes sense. Meanwhile this robotics exhibit has neat interactive stuff. 

Fun!

Other exhibits include: ferromagnetic fluids, freight transport (which is better than personal transport, at least if you're not shipping breakables), mermaid biology, and Molecular Bonds.

Why is Molecular Bonds capitalized?

Because it's an Exciting!!! exhibit for mostly kids. 

Awww, cute. Hi merkids!

Aliens turn out to be more exciting than molecular bonds!

They wouldn't want to distract the merkids from learning! Suppose the aliens talk about molecular bonds?

WHOOOOOOAAAAAAH.

Parents from other parts of the museum start to herd their kids in the direction of the educational aliens. 

These particular aliens aren't molecular bond experts but they know enough to muddle through!
