About 2 weeks ago, I was looking around the Web for the BIGGEST sky rocket

that I could get shipped to me via common freight carrier.  I located a

fireworks importer in Wisconsin who had this mondo sky rocket -- biggest

thing I had ever seen -- called a SkyDragon.  These things are 48 inches

tall and are mounted on a 1/2-inch wooden dowel. Pure aerospace engineering.

 

I plopped down a bunch of money and had him send me two cases of these

things.  They arrived at the freight dock a few days ago and I had to

drive the van over to pick them up.   Two boxes each 2 feet by 2 feet by

4 feet in size containing 80 rockets each.   The 'Class 4 Explosives'

sticker on the side of each box was a real bonus.  I am gonna have to save

them for the scrapbook.

 

That night, me and the kiddos had a gen-u-ine rocket launch ceremony.  I

placed one of these beauties in a liter-size glass bottle and the bottle

fell over.  Hmmmm-- this thing was waaay too big.  I looked around the

shop for a pipe to set it in, but realized that the only dirt I could

drive the pipe into was in plain sight of my neighbor's house.  I knew he

was a cool guy, but I didn't want him to call the cops.  You see --

'projectile-type' fireworks are totally illegal in this county.  I was

surprised that the Buncombe County Sheriff Department wasn't waiting for

me at the loading dock when I picked these things up.  Anyhow, I finally

rigged a launch pad by prying up one of the driveway drain grates with a

crowbar and sitting the stick into the deep pit.  Looked sorta like an

ICBM silo with its hardened lid slid aside.

 

I asked which of my three kids wanted to light the fuse, but all took a

few steps back and politely declined.  Chicken-shits.  Kids just aren't

made the same nowadays.  They fulfill their danger quotient by shooting

bad guys in video games.  About as far from real danger as you can get,

if you ask me.  I told the little weenies to stand back as I bent to light

the device with a Bic lighter.  The lady at the fireworks importer

promised me that  these things would NOT make any noise.  I told her that

they HAD to be relatively quiet so I could shoot them off in my

neighborhood without causing "undue alarm".  She said I wouldn't have any

problem.  I emphasized the particular legal problems I would have if there

were any type of loud report at apogee. I emphasized the fact that I lived

right next to a National Park and that any type of firework that was

discharged or assumed to be discharged on that property would get me sent

before a FEDERAL judge right before I got sent to the COUNTY judge.  She

again assured me I would have no problem.

 

That lying bitch.

 

That rocket engine had a burn time about as long as any I had EVER seen,

and the ascent echoed off the surrounding trees.  Diamond shock pattern

extended from the back end.  It kept going and going and going.  When it

hit apogee at about 1000 feet, the rocket disintegrated into a huge shower

of silent red sparks.  Pretty cool, I thought ... until the shower of

sparks burned out and suddenly transformed into a cloud of EXTREMELY

bright and loud explosions. The kids scrambled into the back door "Three

Stooges" style (ie: where all three try to get through the same closed

door at once) and left me standing in the smoking haze waiting for the

cops to arrive. The dogs that live along our street were all barking their

heads off at the apparition they had just witnessed in the night sky.

 

That ended the fireworks test for the night.

 

The next day, my oldest son Doug and I decided we were gonna "neuter" one

of the rockets so it wouldn't make any noise.  I took him into the closet

where I store the gardening tools and he saw these two huge cases of

fireworks standing there.  The kid went nuts.  He wanted to open BOTH

boxes so he could see what all 159 rockets looked like lined up next to

each other.  This kid has promise.  I told him: "Since mom only thinks I

have a few of these things lying around, maybe that wasn't such a good

idea." He mulled that over for a few seconds, then gave me a real big

smile in agreement.  We pulled one of the rockets out of the box and

re-locked the closet door.  He and I both sat down on the driveway and

proceeded to take it apart. It was a standard issue big-ass Chinese sky

rocket.  I bet they used these to kill people 500 years ago.  As I sat

there taking layer after layer of paper off, his brain was filling with

the details of construction. Tissue, cardboard, plastic, fuses...etc.

Realizing that he was mentally storing the design for some future project

sorta made me shudder.    All I was thinking was the fact that this thing

was probably put together by a political prisoner in a hellhole somewhere

who is probably gonna get "executed" so they can sell his internal organs

on the transplant market.  Probably not too far from the facts, but I

managed to do a bit of explaining to him from the standpoint of aerospace

engineering regarding how the thing worked.  Doug is probably the only

4th grader in the U.S. who can now describe the principle of thrust using

a control volume model.

 

The rocket was pretty simple.  It had a very large booster engine topped

with a warhead that contained the red sparkly things that exploded.

Removing the warhead was as simple as giving a quick twist, and I assumed

the neutered rocket would fly higher without the payload.  I was correct.

Doug and I did a daylight "stealth" test and were able to add about 50%

to the altitude attained the previous night.  We decided to modify four

more rockets and put them aside in the closet for easy access.  When this

was done, Doug had a jar full of stuff that came out of the warheads

including: 12 fuses about 3-inches long each, some paper, 4 plastic

nosecones and a big handful of these little black balls about the size of

12-gauge buckshot that turned out to be the 'red sparkly popper things'.

It appeared that the outer layer was a simple gunpowder coating designed

to quickly burn off as red shower of sparks.  I surmised that the inner

core had some kind of magnesium thermite that gave off an intense white

light and a loud bang.  Pretty cool if you ask me.  Lots of energy packed

into one teeny little ball.

 

I didn't want to see the popper thingies go to waste, so I told Doug we

were gonna put them in a hole in the ground and set them off.  He gave me

another big smile.  It's amazing how kids think alike... even when

separated by 30 years.  As I was digging a shallow hole with my hand, Doug

asked if it would be alright to put an army man next to these things so

that "When they go off, it would look like he was getting shot with a

machine gun".  Dang.... exactly what I was thinking.  I agreed and he ran

off to his room to dig something out of the mess.  He returned in about

3 seconds, out of breath and  holding a cheap plastic imitation of Robert

E. Lee on horseback and a Civil War cannon.  I pointed out that they

didn't have true machine guns in the Civil War, but we would overlook this

for the purpose of the demonstration.  He handed me the action figure and

I placed it and the cannon next to a rather large pile of black beads from

which a few of the fuses extended.  I figured that three inches of fuse

would take 2 seconds to burn, so I had at least that amount of time to

stand up and take a few steps back.  I neglected to recount the night

before... when the warhead ignited IMMEDIATELY upon reaching apogee.

Tricky Chinese.  They had installed extremely fast-burning fuse in these

things and that fact totally escaped me.  I squatted next to Robert Lee

and gave a short eulogy.  Doug laughed.  I took the trusty Bic lighter

and placed it next to the fuse.  One flick got the lighter going and THIS

IMAGE IS ONE I WILL REMEMBER FOR A LONG TIME. My hand holding a lighter

next to a pile of explosives.  There is usually a short but noticeable

mental pause that occurs immediately before something bad or really stupid

happens.  It is where that little voice in your head says: "You dumbass."

 

The fuse burn time was in the 1/1000ths of a second range.   The pile of

little popper thingy's immediately ignited into a tremendously brilliant

ball of fire.  All I could think was "...th...th....thermite..."

Unfortunately, when they are viewed at ground level, these little popper

thingies become REALLY BIG POPPER THINGIES and have a tendency to jump up

to 15-feet in every direction from their point of ignition.  I

instantaneously became engulfed in a ball of fire that sounded a lot like

being in a half-done bag of Orville Reddenbacher's popcorn.  It was all

over about as fast as I could snap my fingers.  After the smoke cleared,

Doug started laughing his butt off.  That meant I was still in one piece.

Doug does not laugh at dismembered limbs. He said I jumped about 10-feet,

an action that I do not remember.

 

I checked my clothes for burn marks, and found none.  He checked my back

to make sure it was not on fire.  No combustion there.  The driveway was

peppered with black holes where the concrete had been scarred from these

things.  A close one.  Another REAL close one.  My mind ran the tapes

again to re-hash what it had seen.  All I remembered was being inside

something akin to a 30-foot diameter ...... flaming dandelion.  Whew.  We

examined Ol' Robert E. at ground-zero.

 

Instead of a machine-gun peppering, he got nuked.   He and the horse he

rode in on... and his cannon too.  One side was untouched, but the other

side was arc-welded.  Real warfare.  Doug examined it real quiet-like and

then started laughing again.

 

I assume he will remember the finer points of the lesson as he grows

older. When I now speak of "almost being burned beyond recognition" he

will have a slightly better understanding of what I mean.  I hope that

this vivid image tempers the knowledge he now has regarding rocket

construction. Oh well.  After all, if your dad isn't gonna teach you how

to get your ass blown off, who will?
