Fireworks time delay?

I want to set off a few fireworks on the night of my wedding aniversary, and rather than run off and light the fuse, or rely on my dopey brother, I was after a time delay with, say, a watch? So I could set it for 10pm and bamoo.. 10pm we outside enjoying drinks, and a few fireworks go up! I have seen somewhere a guy light a match with a cheap electronic watch using a strand from a ball of steel wool, but I forget exactly what he did and where I saw the video now.. If I could copy that I could use the match to light the fireworks! Any ideas like that would be great.

Explosions for football game

I am a chemistry teacher and I need to make a set of explosions for the football team to run through. The run on the field and the explosions go off on each side of them Any ideas. I may fill a dozen metal coated baloons with hydrogen and, and ignite them with some sort of electric spark strong enough to pepetrate the baloon. I'll put six of them on each side of the path that the team runs out through under the goal post. And how will I make the system to spark them off (electric plug in?)(capacitors, tesla coils, etc.?) thanks

How do I build an extremely cheap, easily mass produced delay for my fireworks effects?

I want to build a delay I can put in-line between fireworks effects. It needs four positions(0 sec, 0.1 sec, 0.25 sec, 0.5 sec), 'power in' connections, and power out connections. We use 22 gauge wire for our power feed from a 24V source. I am looking to make these delays no larger than 2"l x 2" w x 1.5" h not including the delay set knob. As an example - Instead of 10 comets firing off at one time, the delays would allow me to set them off, say, half a second apart. Is there a cheap reliable product already out there and available? Can I take resistors of different ohms and just twist them into the wire?  Thanks for your assistance!

Fireworks+Solar Igniter=?

I saw a very neat instructable for an electronic fireworks igniter, and it linked me to another one with plans for a fireworks igniter (https://www.instructables.com/id/Fireworks-Igniter/). In the effort of saving time couldn't you use solar igniters for model rockets to get the same affect, or are they not enough to start the fuse?

Low-tech fireworks in China

Out in Naunquan, China the villagers use molten iron to celebrate instead of fireworks. The tradition dates back some 500 years when the blacksmiths of the day couldn't afford fireworks and did this instead. While there's only one color to work with, the effect is pretty stunning and a lot more in-your-face without, you know, melting your face off if you don't get too close.via Gizmodo

Black Powder for use in fireworks

I want to get into pyrotechnics as a hobby, and i thought i would start with rocketry. So my questions are: What is the best for a lifting charge for fireworks or a rocket, very very fine particles, or coarse granules? i read somewhere on the internet that granules are best, but all over instructables it says to grind it really well. And also, would adding steel powder/magnesium powder to enhance the spark effects alter the BP? like would magnesium make it more sensitive? Please answer, Thanks.

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?

Then we had the idea to add 6 volt lights and an organized switch setup. But we came across the issue of the circut bypassing our negative lead for our 6 light by the positive lead from the 5 light going to switch 1 so therefore basicly switch 7 isnt needed exept to light-up light 6. So now we need help on how to prevent this issue from happening. please help and thanx- Jarred

Will a steel wool strain run between a 9 volt battery be able to ignite certain materials?

I am working on using a 9 volt batery if not larger run through wires to aligator clips with steel wool pinched in the clips. I am using it for fireworks. I would like to know if the quick glow of the steel wool would be enough to ignite 2 different materials before it burns out. These materials are 1. Gunpowder Fuse 2. Aerosol hair spray (rather safe then sorry on the potato cannon for test usage)... I am debating wether or not i need that with a primer to make a longer last heat. If so, any suggestions on what kind of primer and how to secure it to the steel wool grain? I have tested the 9 volt running to the steel wool and it does glow and burn itself out but it does not seem to last long or even enough to ignite a paper towel.

Is it safe to make your own mortar tube? Answered

A friend and I are putting on a (legal) fireworks show tonight with commercial fireworks. I haven't finished my fireworks ignitor yet, so we're going to be lighting the fireworks with punks and running away. We're going to set up two "stations", one for each of us so one person can set something up while another sets something off. The problem is, the mortar set we bought only comes with one tube. I'm considering making another one out of PVC of the same size as the cardboard mortar tube, but this concern my friend. Is this unsafe, even if I stabilize the PVC and if it's the same size as the original tube? 7/6/10 UPDATE: I know it's past the fourth, but I'm still interested in kowing the answer. Thanks, Noahh

what do i need to do to use sparkler fountain black powder in a homemade fuse?

Hi, a fireworks sparkler fountain that i had lying around in my room has dropped its contents as the base clay stuff crumbled away, and what i was left with was a paper case full of fountain powder. the kind of fountain is the kkind that is it a paper tube like normal fireworks, but make a spray of sparks fames and colours of the ground, not a sparkler stick, now sparkler fountain powder isnt like gun powder, this stuff burns slowly, probably because it has less oxidizer. what i need to know, is what i should do to the powder to make it suitable to use as normal black powder when making a fuse using dextrin in the proportions 10/1. i have access to a large amount of potassium nitrate, do i perhaps need to add more of it to the sparkler powder.

Can someone help me with this circuit? Answered

I'm working on a fireworks ignitor based off of Bill Gurstelle's design in his book Absinthe and Flamethrowers, and I'm having some trouble. Instead of two switches, mine has three switches.  Like Bill's design, it runs off of eight AA batteries. One end of the battery pack goes to a toggle switch and a keylock switch, and the other goes to a pushbutton. They both end at a bolt. I have two long wires with alligator clips on both ends. Each clip clips to the bolt, then to a piece of nichrome wire which is wrapped around a fuse. In theory, when all of the switches are flipped, the nichrome wire lights the fuse. But this isn't happening. I've tested all of the switches, and they all work. The bolts and the nuts holding them in place both conduct electricity, but no power is arriving at the bolts. All of the components were purchased from Electronic Goldmine, except for the battery pack, which I bought at Radioshack. The ignitor is housed in a wooden (and therefore nonconductive) box. What's wrong?  (Attached is an awful drawing/collage I did of the circuit. If you need a picture of the machine itself, I can take a picture.) Thanks, Noahh

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.)
