How do i make extreme firecracker that will do REALLY BIG BOOM?

I found a store in nearby that selling fertilizers and stuff for pyrotechniks, So i dont think there will be a problem of getting the ingridients i need. I want it very very loud and i will explain it to you why: In israel, we celebrate purim by wearing custums and disguise and of course using firecrackers, you need to understand somthing, there is a "law", somthing "between the lines" that the more boom your firecracker made, the more respect it is! meaning the more you enjoy and love purim, so in purim, childrens (13+) and adults are going to buy firecrackers and try to "show off" to their friands that they celebrating purim and using firecrackers. As you guys understand I dont want it to fly, or makes colors , sing or dance. My plane and wish is that it will go BOOM, and i mean it, and the bigger Boom it makes, it's the better!! I already have expirience about making firecrackers and explosives so no worry about the safety thing. P.S sorry if it was too long, i just wanted to give you the prespective and the feeling of the most happy holiday in the jewish religion and colture :D

What is the white powder in firecrackers?

I took apart some basic firecrackers, they have a green fuse, waterproof, etc. So inside, I found some grey-ish powder (suspect it is Gunpowder) and a lot more white powder. The Firecrackers do not give of a huge flash, so I am asking. What is the white powder, what does it do, and should I keep it? (Please no answers like "You shouldn't play around with that" and other negative responses. I am looking from a makers point of view.)

cheap time bomb (fireworks detonator)

Heres my idea: Take a cheap dollarstore or walmart watch with an alarm. wire a capacitor where the little speaker/beeper thing it would store up a small charge and then have it arc or a fuse to light it. so you set the alarm for the time you want it to go off, it goes off, builds a charge, arcs over the fuse and lights the roman candle, firecrackers, whatever you want. would this work? are there any ways of boosting the power of the arc or making the fuse light easier?

DIY airsoft grenade that isn't a wad of bb's duct taped to a firecracker?

 Okay, so here's what I'm thinking; an aluminum rod with holes in the sides for the bb's, the holes are a little larger than the bb's, and have a styrofoam chunk in each of them to hold the bb's in. Then a hole the size of the CO2 canister in the middle. I haven't worked out the timing mechanism yet, or even started to, but the firing mechanism would be a spring attached to a hammer with a spike on the end of it, pull the pin, hammer hits the co2 canister, boom. Any help/suggestions here?

How can I make exploding cupcakes?

This is for my halloween costume this year (i won't say what it is until i finish it and put up an instructable of my own, haha!) i had two ideas for explosive tasty confections: either using little firecrackers as candles, or putting some type of exploding pellet or capsule inside the cupcakes that would explode on impact. a friend told me about something that may or may not contain mercury, or i suppose it could have been magnesium since it's so flammable...it comes in little spheres/pellets/capsules that probably contain some of the same ingredients as flash powder, only in a more concentrated form. if such a thing exists, i would just bake cupcakes and squish the capsules into the bottoms of the cupcakes. i'm open to any other ideas. help please!

what makes the best flash powder?potassium permanganate or nitrate?

Hello, currently performing operation "shoe candle" , for yowee. this operation is basically videoing the destruction of various fruit using flash powder or hmtd in a small 1-2ml glass vial. now, i have chosen my prefered explosive to be flash powder because after seeing the damage hmtd does when detonated in this way, i became frightful for my own safety, considering it lifted 1kg of dirt 30cm into the air and destabilizing it and making it fell as if it were dug up and loosly fille din again. ANYWAY i have come across a slight problem because i cant readily make aluminim powder enough to experiment with flash powder concuctions, and also i have about 4kg of finely powderd potassium nitrate lying around, wheras permanganate costs $10 for 25g at the pharmacy i would like to ask you instructables members, would flash powder made with potassium nitrate combust better than flash powder made with potassium permanganate the current mix i am using is 3 parts permanganate / 2 parts aluminium powder/ 1 part sulfur apparently this is the recipe for the old M-80's firecrackers i want to know if a equal or more powerful mix can be used by using potassium nitrate whoever answers will receive a best answer from me

I want to build a(quick simple design=least amount of parts)compact/portable inverter use a 9v battery making 22volts?

I always wanted to make a type of SILENT portable hand held lighter/ignition source that doesn't use flints or fuel that can ignite any firecracker fuses, cigarettes, or generate enough heat in a quick time. So what i did was part out my moms old 1875watt hair dryer that she burnt out the motor to and i kept the spring coils portion that used to make the air blown hotter. I cut a 1inch piece of them heat coils, mounted it to an old parted out lighter reservoir and wired the piece up with a momentary slider type switch on the side of the reservoir that is being my safe to the touch so i can hold portion -  to a cigarette car lighter type plug adapter and plugged it to my car battery jumper pack that has the cigarette lighter receptacle.(i did this as it was my only option to a DC type of power because at the time i didn't have batteries & unsure how much it would need) now i tested it by sliding the slider switch on and in less than 7seconds it had lit up bright orange and really hot. Okay cool its almost exactly what i wanted but i don't want to have to plug it in to anything or carry around a huge heavy battery pack. So i tried to connect a 9 volt battery to it since that would in fact make it compact & portable completing my design,  but when i push the slider switch to on it took really long to generate any heat(barely even lit up)and killed the battery after holding it on to get any type of heat for like 4-5minutes. I need it to lit up to its bright orange HOT in that 7seconds or less and i need or would like it to have longevity or more then 1 time use. http://i126.photobucket.com/albums/p97/krax78/lighteridea.png

That didn't just happen, did my oscilloscope die!?!? How??? Repairable????

I went to my workbench today to discover that my BK Precision 30MHz analog scope has stopped working. Symptoms: ❶  Still shows a trace ❷  The trace does draw across the screen*  ❸  The horizontal time base seems to work ❹  10x horizontal magnification seems to work ❻  XY mode only draws in the X direction ❼  Waveforms do not show up, for either chA or chB ❽  Triggering seems to work (it causes the trace to draw more/less frequently. No vertical deflection)  ❾   Vertical controls for both channels have stopped working ❿   Dual trace shows only one trace ⓫   I have not been able to do anything to make the trace move up and down, vertical deflection is definitely shot. ⓬   * When changing the timebase, I noticed that the length of the trace horizontally gets shorter, and when a signal is present, or the vertical position for the appropriate channel is twiddled, it becomes the right length, within certain ranges. ⓭    When I was reaching for a powerstrip to turn off power to the lab the previous night, I heard a loud buzz, similar to that of the degaussing on a old computer monitor, but louder. no sparks or anything were visible as I recall. scared the crap outta-me, and I could not figure out what had happened. First thought was that maybe somewhere there was a live mains exposed somewhere that had shorted to ground or neutral. That was quickly dismissed since nothing was exposed like that, and also it would have popped the circuit breaker, and instead would have sounded like a firecracker. This sounded more like a small transformer failing. Also the same day, I have been messing with a tesla coil circuit (my beefed up slayer exciter) and the probes were sitting here by not connected picking up interference. They were in 10X mode, I do not remember the volts per division, however. I do recall a trace being shown on the display the previous day. With these symptoms, I think the issue has to do with the vertical control on the CRT, and perhaps another, separate issue with the horizontal time base control, or possibly triggering. I think I might do a teardown on it to see if there is anything obvious that has failed, such as a charred coil. Then I will need to figure out what had caused the issue. It is obviously something gone horribly, horribly wrong with vertical deflection or something of the like. I will have a look at the schematic and see what I can learn about the operation of the scope. I am glad I do have the user manual and schematics, so it should be straightforward, it is a nearly 100% BJT design. The scope was used and old, and lacked a lot of features, such as cursors and frequincy counters. Perhaps it is time for a digital upgrade anyway... http://www.amazon.com/gp/product/B00N222I6C/ref=s9_simh_gw_p504_d15_i1?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=desktop-1&pf_rd_r=1VEC8M45MB2T9REXCR7N&pf_rd_t=36701&pf_rd_p=2079475242&pf_rd_i=desktop
