  1. Yes, kosher salt is best: most table salt like Morton use anticaking agents which don't dissolve in water. Morton used this as a selling point, saying "When it rains, it pours," indicating that the salt runs freely in humid conditions and doesn't clog up.

  2. Nice explanation. Also good for chemical investigations. (Though not as meticulously documented as good science demands.) As far as creating a lava lamp, I'll leave that to dedicated tinkerers like you, and I'll just buy a nice one.
