My chem teacher decided to do a flour bomb in class the other day. 
Using Lycodium powder.  he did it without the lid on(Using an old milk
can) and was rather underwhelmed with the results.  So I suggested
putting the lid on.  In addiotion he came up with the idea of putting in
more powder.  More powder, decent confinement (the lid was a bit
difficult to get on.)  led to a rather impressive explosion.  It shot
the lid 10' or so straight up and doubled the size of the collumn of
flame and he was afraid that nothing would happen.

Yes and no. Explosions are rapid expansions of gas. The gas pressure can
be generated slowly - as with dry ice evaporating, by burning rapidly
(deflagration) - as with black powder, by detonation of compounds - as
with high explosives, or by the fission or fusion of atoms, as with the
thermonuclear weapons.

The fuse does not explode. It is the primary explosive which explodes.
This explosion provides the shock wave necessary to initiate the high
explosive.

Well, I've been doing that 'BIC' lighter thing since I was 12. I
never once got more than a rocket effect. There was no explosion,
just a lighter burning itself until there was a small enough hole
for the gases to escape... then a quick swooshing sound and the 
lighter would propell itself uncontrolably around on the ground.
But like I said, there was NEVER once an explosion or even a 'pop' 
sound. I did this about 40 times between the ages of 12 and 16...
And, that is my 2 cents worth...

Gee, I've been using the net for some 3 months now, and I just *now* found
this group. (argh!)

Oh-well better late than never.

I'm sorry if the following are quite simple or stupid questions but there
is no FAQ.

If the is a FAQ could someone send me a copy? If not, make one?

I noticed the mention of Oxygen-acetelyne (sp?) as an explosive.
I also know from experience that this combo tends to be rather volitile.
I belive acetelyne is unstable over 14 psi. (memory from high school shop
safety instuction just a *little* fuzy on exact value, and it is 03:00 local
time.)

I recal some one once told me that a volume equivalent to an inflated
football (they weren't too imagiative), that if exploded (no details on
method, but I've got my own ideas that may/may not work), could produce
enough force to shatter windows aprox. 1/4 km away.

Is this anywhere near realistic?

Also, can acetelyne be ignited by an electic (magneto induced) spark?

Fellow skydivers,

If you are going to the next Boogie-Til-Ya-Puke, which is going to
be on the 21st and 22nd of November, and you pass by St. Louis,
a ride from there would be greatly appreciated.
Or, if you just happen to drive between St. Louis and Memphis on
the 20th of November (Friday), that would be just as good.
Please reply directly to egyed@lns598.tn.cornell.edu  .

Put your rig in a gearbag with no other stuff so it will fit
under the seat in front of you.  Do not say you have a rig.
Just put it on the conveyor belt for carry on luggage.
 
If you get asked, say it is a SPORT parachute.  You might
have to call ahead to a reservation agent for that airline
and get the page # of the regulation that allows parachutes
as carry ons.   Most allow it except one but I forget which one.
 
Parachutist and Skydiving magazine have published the reg #'s
of the various airlines that allow parachutes.

To bad that the money end of things has to creep in and spoil it all
sometimes. Your experience level may be low but with 1000 jumps under
his belt, diving with your buddy is a great idea. Stay with it as there
is no other sport like this one anywhere. Adrenalin rushes are

Bent reserve pins and micro-cracks in the 3-ring release come
to mind.  Also, there's plenty of dirt on the transfer carts
and surfaces anywhere along the way may have sharp edges to rip
through your gear bag.

To be fair to you, it is unlikely that anything will happen to
your gear and it's just a personal preference of mine to carry
fragile stuff, but I've seen too many objects that say FRAGILE
in big letters with big dents in it, too many boxes that say
THIS END UP with the arrow pointing down, and too many foot
prints on luggage to believe that my parachute would be safe.

Dan Briggs did a great job of summarizing the World Freestyle Competition, I
just wanted to add a couple of comments.  The freestylist with the streamers
from ankle to wrist wasn't female, it was Steve Wood, of Steveadorable fame.
The Steveadorable's have traditionally made a fairly elaborate entry video,
this year's was about 15 minutes long and definately worth seeing. After Akio
got hurt, Peter Raymond stepped in and filmed Kokobu. I'm not sure, but I 
think it was Amy Baylie who did the Maverick pinwheel move.

About the two round system - after last year's competition we had a meeting
with all the competitors to discuss what changes they wanted and to set the
rules for this year's meet. There are basically two schools 1) freestyle is
free and there is no wrong way to do it, it can't be judged and you shouldnt
have compulsory moves. 2) we have to define every move in great detail and
create a code of points (like gymnastics) so the judging is completely
standardized - if you do a T and your back leg is bent 10 degrees then that
is a 'minor' and you get this many points off your score etc. I personally
think that there are problems with both extremes. We put the compulsories in
orginally to give the judges something to compare with. It was very very very
difficult to watch and score the Italian team and then watch a guy with red
fuzzy feet and try to score that! I think next year the compulsory round will
be a predefined routine and the free round will be completely free. I don't
see any contradiction with compulsory freestyle moves - dancers and musicians
both have competitions and they are judged on technique (compulsories ) AND
musicality/artistic expression. 

There is a small chance the freestyle video will be available before the TV
show airs, if so I'll post the information.

I think it's only a matter of time before the FAA really cracks
down on DZs and the lack of seatbelt use.  We've had two crashes
this year, which will most likely double the number of dead skydivers
for the year.  The seatbelt issue, and the packing issue, are looked
at mostly as jokes at every DZ I've been.

I'd personally welcome these restrains, and hope they will be 
inexpensive and mandatory on all jump aircraft.  Face it, seat belts
are just not going to save you in a plane crash, but your harness might.
As long as the devices are flexible, allow some minimal movement within
the aircraft, and can be disconnected very quickly, I see no problem
using one.

Everybody has to be restrained for these things to work--the danger is
getting smashed by a human projectile, or making worse what could already
be a very dangerous weight and balance.

Originator: eap@everest.Stanford.EDU
Organization: Center for Integrated Systems, Stanford University, California
Date: Tue, 10 Nov 92 19:26:52 GMT


	TRENTON, N.J. (UPI) -- New Jersey's labor commissioner said Monday he
is considering a total ban on commercial bungee operations in the state.
	Operators who testified at a regional hearing on the amusements
defended their rides as safe. But some called for government regulation
and inspection, saying they do not want the business to get a bad
reputation.
	Labor Commissioner Raymond Bramucci, who chaired the hearing, said he
must decide what, if any, regulations will make the rides safer, adding
that a ban is still an option.
	Bungee operators charge around $50 to thrill-seekers who jump from a
tower or crane, their fall broken by an elastic cord. At least 11 bungee
deaths have been reported worldwide.
	Because the sport is so new, it is relatively unregulated. In New
Jersey, for example, it is governed only by the regulations for
amusement park rides.
	New Jersey did shut down all bungee jumps briefly during the summer
after a Delaware nurse was severely injured on a jump in North Wildwood,
a crane toppled over during a high wind in Wildwood and a bridal couple
in Atlantic City held an unauthorized double jump as part of their
wedding. Most rides were allowed to reopen after inspections.
	The most dramatic testimony came from a doctor who treated the nurse.
She broke her spinal cord when she landed on a protective airbag, after
jumping on a bungee cord that was too long for her weight.
	``When you hit your head like that, forgive the word, but it was like
splat,'' said Dr. Maurice Davidson. ``Why her brains were not all over
the ground, I don't know.''
	Without the airbag, his patient would have been dead, Davidson said.
	Operators were divided on whether bungee jumping is a sport, with
participants knowingly taking the same kind of risks they would take
jumping by parachute or ballooning, or an amusement park ride. Davidson,
who has embarked on a study of bungee injuries, said jumpers have no
control over the situation once they take off.

I've just come back from a sky-diving holiday around the world,did the

what it was (especially the Russians and Americans-but only at L.A.X
and Boston!!) but otherwise it was never more than 4' away from me.
Except when I used the head!
Besides that feeling (maybe false sense) of security in having it close
by,there is no way in hell I'm going to trust my brand new rig to be
manhandled by some of the "expert" baggage handlers i saw. They were
mostly the thumb in bum,mind in neutral bunch.

Hello, again.

My new friend Brent has a rig for sale and has asked me to post it for him,
since he doesn't have access to rec.skydiving.  Sounds like his employer
doesn't see it as essential business, so I am again acting as go-between.
Please answer him directly (e-mail address below) as I know nothing about
this rig.

I jumped at Skydive Colorado yesterday after having been five days in Eloy.
It was so different! Not to mention cold.  Is it true (as it seemed to me)
that you fly different in cold dry air at altitude than in warm air at a
lower elevation?  Hard to tell for me, but I find it *easier* to fly in
cold air.  But maybe it was just being back with old RW friends... just
wondering.

Also, you might want to state what format you want the tape in, since
chances are that you don't have an NTSC video recorder.

Which reminds me. Does anyone know where I can go to get an NTSC tape

this system, or for some reason has better opportunities getting it

Canadians?

Well, the S&TA certainly could have grounded him at Eloy, and I think some
would have.  Granted, as the weekend was almost over in this case it
wouldn't have made a lot of difference for that trip.  But if my friend had
really copped an attitude (which he didn't) it surely would have been
within the S&TA's authority to ground him at Eloy for as long as he
pleased.

My impression is that most DZ owners will back up the S&TA completely
on questions of safety and discipline.  Or is that not true in your
experience?
