Explosive tip arrows?

I have been looking for a way to make archery more intresting so i came up with the idea of explosive tip arrows but i got afew qustions. 1st of all i know this is not really safe but i can insure all of the instructables community i will use them responably. What would be the best type of explosive to use?? would it be better to use an explosive that will explode with the inpact or rig a primer in there somewhere. My next qustion is what do you guys think will be the best idea to house the explosives in?? should i make a tip to put it in?? If so what would be a good design?? or should i rig the explosives inside the arrow?? Thanks for everyones input.

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

You know those party poppers? The ones you throw on the ground and they make a tiny spark. How do you make those?

One time i unwrapped one and these rock/crystals came out. Any idea what they are and how to make them. I though it was phosphorus and another compound that ignited it. But I still have no clue. I had once seen something on a website called the anarchists cookbook. But the website was quickly deleted...

What is the optimum amount of rubbing alcohol for explosions?

I am working on a mini-cannon based project. The cannon has a chamber with interior volume of 15.2 cubic inches. For propellant I am using rubbing alcohol (isopropyl alcohol) that is electronically ignited. The barrel on this gun is about 2 feet of 6mm tubing, designed to shoot Airsoft BBs. I was wondering if anyone knows what the ideal amount of rubbing alcohol to use was (I am using 70% alcohol now, but i can get at least 90% at the store). I could also possibly use butane or propane, if that is better. I went on the internet and looked up the stoichiometric ratio for isopropyl alcohol, but that just told me "1mol fuel to 4.5 mol oxygen at 100 percent concentration." I am not mathematically or scientifically capable of turning that bit of info into a usable amount.

ammonium nitrate and water get cold. how can i make a cold explosion

I need a chemical compound that makes extream presure in a millasectond, like an explosion but must remain cold. I know that by adding ammonium nitrate and water the compound gets cold. so my question is by using ammonium nitrate and other then water can I use to make extream pressure build up in a short time while still being cold. this question is not for any explosive device to cause harm to anyone or thing. just wondering if a cold explosive could be possiable.

Music Video Help?

Me and my friends are making a music video for a class we chose the song "A Dirge For The Underground" by Attica! Attica! We have most of it  done, but we are having problems with the last shot, we are doing of an explosion (not with actual bombs, just implying there are bombs). We don't mean like Die Hard, Action Movie, Jump to the Ground at the last second explosion, but the explosions you traditionally see when a building explodes, lot of smoke and debris as opposed to fire and a slightly sooty hero/heroine. It's just going to be blowing a lot of immediate debris and smoke blowing outward and then smoke drifting up. Best idea we've had so far is rent a big ass fan and set up a temporary business of cleaning out fires lol. We unfortunately do not have access to the media lab so digital effects are unfortunately not an option. Any better ideas (that don't damage the location, the owner would be pisssssssssssssed)?

Are there other ways to cool an object to 77 K (−196 °C; −321 °F) without use of cryogenic fluids, like liquid nitrogen?

 I am looking for a way to be able to keep an object below 77 K, while maintaining an airtight container. This cannot be obtained with cryogenic fluids like liquid nitrogen, as it becomes highly explosive and dangerous. Therefore, I need a way to keep an object below 77 K in an airtight container, safely.

How do I ignite this smoke cartrige with a shorter battery than AA and with no explosives? Answered

Updated question: As using nichrome wire does not seem to work in my application, I am looking for ideas how to ignite this smoke cartige, electrically and with no explosives and with a battery shorter than AA. Thanks! Hi, First, I have very little experience in electronics. I am familiar with Ohm's law but don't undestand it fully in every situation. However, I'm developing a product in which I need to make a nichrome wire glow for at least 5 seconds, with help of a battery. The lenght of the wire must be at least 5 cm and must be at least 0.2 mm diamater. (Longer/bigger is even better). I am trying to find the smallest battery possible, due to very limited space. After 5 seconds, it doesn't matter if the battery goes flat, as long as it doesn't explode, catch fire or anything else unpleasant. I have already read through every forum with similar questions like mine, and have understood that I need a battery that can deliver enough current. I therefore have an idea that I maybe could use a high capacity coin cell battery of model CR2477 (1000 mAh, 3 V). However, as I, due to my limited knowledge in electronics, I cannot predict what will happen to this battery and I'm too scared to try. I also found this website that let's you calculate, for example current requirement with a given wire: http://www.jacobs-online.biz/nichrome/NichromeCalc.html If I punch in the following data: 5 cm length, 32 gage, 2 volts, I get a current requirement of 1.15 Amps. I entered 2 volts because of internal resistance of the battery, don't know if that was correct. Will the CR2477 battery be able to supply 1.15 Amps for 5 seconds? Will anything not nice happen to it? In the data sheet of the battery I read a maximum pulse current of 25mA, which makes me think that it will not work. But at the same time, I know that a standard 9V battery would work, and this has less capacity in mAh (though higher current). Can somebody help me understand? Thanks!

Compressing home made biogas

Hi I'm working on a project where we are using an anaerobic digester along with a series of gas scrubbers that yields biogas containing roughly 80% methane (ch4) and 20% oxygen. I know that this proportion of methane is well above the upper explosive limit of methane (about 15% methane by volume) but the presence of that much oxygen makes me nervous.  Am I going to have trouble compressing this gas mixture without blowing a new hole in my head? I am planning on compressing the purified biogas to about 20psi at between 60-80 degrees farenheight and in a respectably blast proof gas container.  please help! (Trying to help our planet!)

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!

Rockford Fosgate R500X1D repair help?

I have a Rockford Fosgate R500X1D that is having issues. It lasted a while but then there was a loud "pop". It still worked, but it could only go so far. I took it apart and found a bulging capacitor. I have already replaced the capacitor with one that had the same specs. After the swap, It worked for a few minutes but then there was another "pop". I took it apart again and found a discharge(?)/burn(?)/explosion(?) mark on the bottom of the enclosure right beneath the new capacitor. I can't recall if there was one there before or not. This time, however, the capacitor seems to be fine but the amp is still acting up and i'm not too sure what the problem is. Any help or ideas would be appreciated. Thanks.

How do I make a circuit that will flash and beep faster and faster?

To elaborate, I want to make a prop for a convention that looks and acts like a pipe bomb from Left 4 Dead. I was planning on making it out a piece of ~1-2 inch diameter PVC pipe about 6 or 8 inches long. The key is to be able to turn it on, have it beep and flash, and then throw it and have it beep and flash faster and faster until it either just turns off or, even better, makes an explosion sound. It need only run for 10 or 15 seconds at most. The prop in the game has external wiring and whatnot, but I can always add that cosmetically later. Thnaks for any tips.

IC ENGINES?

I was thinking that what will happen if we arrange inlet & exhaust valves on the piston (spark plug remaining on cylinder head)? i think that may be by using metal foam on the cylinder head the knocking of the engine might decrease. please assume that somehow i use proper mechanisms for valve timing & they dont have any appreciable effect on the piston. just consider that the weight of the valves is added to the piston. i was wondering that this might increase the efficiency of the engine because suction will take place more slowly (so it will near a reversible process, so efficiency will increase) & force of the explosion will be better. please you ppl; if anybody can give me satisfactorily explanatory answers, do reply! :)
