SOLVED. YA Fantasy, set under the sea with an undersea civilisation, a boy goes down from the surface. Read around 1987. [s]

Hoping someone can help as this has been bugging me on/off for years. I read this at school, around 1987 - and I have have a feeling it was oldish even then, but pretty sure it was post war. I can recall there being some sort of sweet or candy that expanded when chewed and popped in your mouth, and also either a shower that threw you up in the air when you used it, or did the same when drying you, or possibly both. I have a feeling it was "boy comes down from the surface and meets girl who shows him about" sort of affair, but I'm really at a loss as to what it actually was! Hope someone can put me out of my misery :)

I don't recall candy or a shower being involved, but Crisis on Conshelf Ten by Monica Hughes could be a possibility.

Thank you :) - no, it's definitely not that. Very much earth based.

Does anything on the Underwater Cities list look familiar?

What's funny to me, having had a quick skim of it, is the slightly misremembered elements. The "candy" was stardew, it didn't explode in his mouth, but it did blow his mind.

Yeah, I didn't remember that either but I reckoned "old book with kid being shown round undersea civilisation" made it worth mentioning!
