Here is a link to the smoke gun blaster fun. Watch carefully as
one smoke ring intercepts another, Some of the rings destruct ,
some bounce and some encircle and enhance by encircling the first
torus ring and accelerate.

WAY COOL... imagine the possibilities ...
...of course, one wonders if Richard isn't thinking about trying
to do something similar in liquid, intead of a gas .... perhaps by
rapdily moving his vortex stirrer up and down in the orthogonal
vector. Methings the tank could not take that kind of stress
however.
