>Paul, Have you tried the thirty minute treatment with a ball that has had a
small air hole put in it? Although I very much like your analysis, could it
be possible that with time and at low temperature the rubber settles into a
potentially more explosive molecular arrangement? Although much less likely
than your explanation, I have seen crystal goblets explode, and it is said
that the glass has cooled in them in such a way that they are under stress.
By the way, I miss the exploratorium and all of you. I am now in Montana,
which is the large state on the end of the earth. Steve Eiger
