So how do I make a bomb from irreversible decisions in a bottle? :confused:

[Got Your Ass!

What I'm actually here to discuss is stupid stuff we did as kids and the future of rockets.

Probably the biggest waste of time on pyro related stuff was mixing black powder with paraffin wax. I eventually added Al powder and didn't notice any notable improvement.

I used to play around with things to make color "stars" as the pros call them, but never got anywhere them. It was about that time shit happened and I abandoned pyro.

However, I never lost an interest in rockets. The future of the rocket as we know it is gone for space exploration. The future is ion thrusters. What I'd like to see developed is an ion thruster that gets it's electricity from a nuclear reactor. The steam used to drive the turbine could simply be routed through a heat exchanger exposed to space. ]

Heh, I never really did anything stupid with pyro when I was a child. I grew up reading Backyard Ballistics on totse, if anything I prevented friends from being idiots.

Rockets and Ion engines eh?

Time for fun with the Biefeld-Brown effect!

I've wanted to make one of these for so long, but I've never gotten the right parts together for the power supply. Perhaps somebody on here will get interested and have better luck.

They've already managed to lift a hamster with one of these :D

So I'm not quite sure what the topic is but here's a story of me as a kid playing with fire.

I was one of those kids that got bored really easily. As one of those strange projects to keep me amused, I made a little stand with a concave metal bowl and filled it with burning rubbing alcohol. Needless to say, this was a bad idea.

After filling the bowl with about a glass full of rubbing alcohol and setting it alight, I stepped out of the room to go clean up. Turns out, I accidentally spilled some, but didn't notice because of the clear flame it was burning with. About 5 minutes later I came back, and my entire wooden desk was on fire. I fucking panicked. I grabbed a pile of dirty laundry, threw that shit in the tub and soaked it and threw it on my desk.

Finally, that shit was out and I thought, "Goddamn that was fucking stupid."

But yeah. True story.

So sexy!

Unfortunately rocketry is my weak point. I have only pressed like 3 rockets and only 1 was really fully successful. I have tooling though and psyco is going to instruct me on how to press awesome whistle, cored BP, and core-less BP rockets at PGI 2009.

I've only tried to make two so far (with no press/tooling), one just sat there and flamed so i put a really tiny exhaust in the next one and, you guessed it, Boom :D .

I attempted to make kno3/sugar fuel twice but burnt it each time (I can't make toffee either) apparently i need to use a pot with a heavy bottom to stop it burning.

As for stupid shit.....
* Was almost permanently singed to some degree, Riding a go cart/bike through a wall for fire was fun (A buddy dumps a cup of petrol onto a small flame just before you get to it)
* Carried detonators loose (With sparklers as fuses!!!) in my inside breast pocket for miles at a time.
* Watched a buddy dump about half a liter of petrol into a 44 gallon drum full of trash only to stand over the top of it while dropping a match in - A new drastically shorter hair cut followed :D .
* Carried around "chlorine bombs" made from 600ml poweraid bottles and chlorine + sugar, the idea being you just unscew the lid, pour in some water, shake and throw. Worked great for about 20-30 then one must have had some water left in it from where i'd washed it out. a mate was carrying it at the time walking up the street in daylight when he proclaims "Fuck! that's hot" and drops the fucking thing at my feet, quite a loud bang followed the second it hit the ground and i got a face (eyes!) full of chlorine granules, that shit hurt.

My most successful rocket exploded. :cool:

I'm willing to bet we all did the same stuff as kids. Modifying fireworks against anything safe and sane. Mixing things that ought not mix. That smell and missing hair.

My earliest memories of fireworks is lighting magic whips (http://www.made-in-china.com/image/2f0j00aMJQmKftgEckM/Magic-Whip-FT-5015-.jpg), just like a crackling ball but linear, like a snake. ;) I threw it out in front of a car that was driving past. Musta been about six or seven years old at that time.

Skip a couple of years. I'm probably eleven now. We're taking apart jumping jacks (http://www.fireworks.com/images/products/J-021.jpg) and making a big pile in the road. Dropped in a lit one and watched 'em all fly around. There was a burned patch of asphalt for a couple years after that. My brother, and our friends would hold a pack and light the fuse then wait for it to burn down, almost light up, and throw the whole pack up in the air. Those little dudes can fly pretty far, right in to open car windows. :eek:

Once I hit my teens it was uncontrollable. Trips to Wyoming, where the laws are looser, and hundreds of dollars worth of smoke and noise. Throwing artillery shells like hand grenades, bottle rocket wars, lobbing smoke balls with lacrosse sticks, shooting our 'bazooka' out of my friend's window, trying to blow up everything we could think of with single wolf pack (http://www.fireworks.com/images/products/F-047.jpg) crackers.

I had a good understanding of how things worked by now, so I tried to make everything better. Wrapping crackers in string and glue and tape. Lighting bottle rockets in sealed bottles. Flipping cakes and catching a purple star in the ass. :cool: It was about this point I began experimenting.

I remember my birthday very well. It was the day I first made BP. Though I had no S or a scale, I did my best. What I got was a slow, slaggy burning gray mixture. I nearly came. I remember it so clearly. I carefully spooned out my KNO3 in to one square of TP and diaper mixed in the charcoal. I put it in a little pill container and dropped in a smoldering piece of paper to ignite it. The clear red flame filled my backyard with smoke, but not the smell I loved. It's been with me since and always will.

I remember my utterly hopeless pursuit in creating black powder. I would always end up just buying massive quantities of safe n sane fireworks, tearing them open, and then filling up a ping pong ball with it. the fourth of july was always fun :D
