First off, not all grades are given for scientific merit or plausibility,
except in Chip's class. Rich gets an A for 1. participation, 2. creativity, 3.
effort, 4. Reason, 5. Reasonably good grammar, 6. Good sportsmanship in the
face of criticism.
So, Rich does not get a poor grade.
I certainly hope no-one is intimidated out of partipation by the criticism.
But I like the Jelly pools.
But I see no reason why salty water could not be a good reflector (pure water
is an insulator). Is a rotating liquid truly parabolic? For all I know it is
hyperbolic, or a catenary (the shape of a hanging chain or rope). Now, so I
don't have to spin it forever, I have to make it salty Jello...
