Hi,

Their old tank is four feet deep of water and they whine that the jet is
eating away at the steel bottom...  In the case of a big sphere, they can
fill it with water to absorb the stream's energy enough after it penetrates
the first surface.  The whole big water filled sphere does have to take a
lot of force over all, but not to bad really...  A really small sphere
would certainly get tricky...  The stream of water has a terrible amount of
energy behind it and it has to go somewhere!!!

This is where the engineers than run these wild machines earn their keep ;-))

Cheers,

         Terry
