[K3CAL] Tennis ball launcher or the likes...

[Richard Terlisner]

a friend in NH used the fishing pole and sinker once.  worked pretty good.
i'd say try that route first, cheap.  if it works you're in like flint!

next step.....build a potato gun.  some pvc pipe, nair hair spray, and a
grill ignitor.  chamber size is critical.  plans on the web.  i worked for
the physics department years ago, one of the profs figured out
muzzle velocity was about 600 ft/sec.  that will definitely work.  just
need to aim high, too low and you'll hit your neighbor's window an
acre over.

a friend * myself made one once.  didn't know if it was firing, so i stood
back, looked down the barrel *(NO POTATO IN IT!!!!!!!!)* as he hit the
ignitor.  ball of flame shot 5' out the front.  one of those times where
they had to peel me off the ceiling with a putty knife again.
