To Julius and Trevor,
Although I am not recommending it, on several field days some of us used a
"mortar" made by by welding a base on a 3" pipe with a small hole in the
rear which was filled up with acetylene and oxygen from an oxy-acetylene
torch. The projectile was a regulation baseball with an eye screw screwed
in, attached to a few hundred feet of thin nylon line. When loaded, the
oxy-acetylene mixture was ignited by the lighted torch. We were looking
for height not distance, and managed to top some 100' trees. Can you
envision an extended double zepp on 40 at 80'?

Somewhere I've seen a design for a compressed air
tennis ball line throwing "gun", which looks like it
could be fun.
cheers,

Although I haven't tried it, one of the larger variety of 'spud guns' may
be useful for this. I have one which fires a spud section around 200
yards when powered by 'high octane' hair spray :-)
The problem would appear to be how to attach the line to the spud. Perhaps
a light basket shaped mesh material loosely arranged over the muzzle of
the gun with a light line attached.
I have just done a swift 'google' , and plans for the combustion and
compressed air versions can be found here http://tinyurl.com/44rwh and at
several other sites.
