Connor & everybody else,
	I have a question about the 'phosphor' inside the balloon, and
about phosphorescent materiels in general.  Apparently, a phosphor absorbs
a high-energy photon, and re-emits low energy photons.  Could someone say
something about how this works?  Are the photons emitted one at a time, or
all together?  What is the typical energy difference/proportion between
absorbed & emitted light.  Finally, is any energy left over?
