While Ron is going with the Bra, jock strap quilt, i want to
construct a piece of functional sculpture for BurningMan.

What  i have in mind is a rocket...a flying phallus, to be
precise.  I want to build one at least six feet tall (1:10
scale) that will achieve about 100 feet of altitude minimum,
300 feet ideally, before flipping around and parachuting
back to earth...or exploding gloriously upon reaching max
altitude.

I have lots of experience handling explosives as i used to
set off several thousand pounds of explosives off a day in
the mountains as a shooter on a siesmic crew in alaska and
wyoming.  I have no experience with rockets or rocket
fuels.  Is my project feasible? Any ideas on fuel or engines
or design sources?

Even if such a large phallus rocket is not feasible, i still
want to build a rocket of some size and do something with
it.
Thanks
steve
