I have three balls. Two are blue and the third is red. I bought
them from a street-vendor a long time ago. They are pretty
solid, as if made from some sort of ceramic, but when struck
together they produce a very loud bang, because some sort of
impact-sensitive explosive is incorporated into
the material of
which they're made. I have used them many, many times and
there is no sign of their explosive power diminishing, so I
assume that they contain an extremely large number of very
small explosive particles.
It occurs to me that this could be the answer to the
disappointment which is inherent in Newton's Cradle - namely
that it goes click-clack for a dozen or so times, then just sighs
If my balls were attached to wires (and I'm sure many of you
would oblige), they could form a sort of perpetual Newton's
Cradle, kept going by regular small detonations.

||Indeed. But those hydrogen atoms are chemically bonded to
other atoms at the moment and you'd need some kind of
fission device to start the reaction.

||That's an ugly, ugly mental image that's going to take a lot of effort to disperse ...
