Inspired by Scroge McDuck, of course. We were discussing how you could not swim in gold coins because they stack together and form into a more solid entity, and are not fluid like water. And then we were talking about ball pits and she asked if she had gold marbles in a swimming pool could she swim in those?
I answered no originally but then realized, I don’t know for sure.

Not answering your question specifically, but your daughter will probably find Mark Rober’s video about [swimming in a hot tub of sand](https://www.youtube.com/watch?v=My4RA5I0FKs&vl=es) absolutely fascinating!
His videos are very child friendly and he explains the physics of what is going on really well.
