How to do a hollywood style explosion

Hey, dose anyone know how to do a Hollywood style explosion. Sort of like the ones in Monty Python and the Holy Grail where there is a large fireball. I have heard of taking a plastic soda bottles and filling them with gas, but I was not very fond of this idea.

Measuring an explosion

While this may not be the best instructable I believe it would be helpful for many people doing science fairs (ie: ME). So here is the question said instructable would answer: How do you measure the force of an explosion, specifically of gases or liquids used in fuels? I have been racking my brain on this but everything i have come up with seems like it would be inaccurate. Thanks for any help

Exploding color pigments - need ideas to make

Hello everyone, I am working on a film project and I need to make small explosions of colored pigments and/or powder. Below is a link to a few sample photos of the affect that I am trying to achieve. http://photogrvphy.com/pedro-aguilar-bang/ I have tried many different techniques from impact to compressed air. But I am not getting the shapes that I am looking for. I am thinking  that the best technique might be some sort of controlled explosion. This could be something detonated within a pile of the powder or potentially (and more complicated) and fully concealed shell that includes the powder. I will primarily be shooting straight down above the powder so it really only needs to explode up and out. And again, these are relatively small blasts. I would estimate the powder blasts in the images from the link are only approximately 2' in width at the most. And help would be greatly appreciated!

Sparklers and the meaning of life

I have been playing with sparklers for ages now the latest experiment was to do several layers of aluminum foil and duct tape around two packets of sparklers and putting some arrow fletchs on them... the last one we tried went across three paddocks and nearly took out a shetland pony :-( we measured it the next day and it came up to 150 metres. However i have allways been looking for explosions... sidetracking slightly here but i actually got an explosion my bro welded up a pyramid the size of a soccer ball i filled it with sparkler dust dad wasnt very happy about the huge hole it left in our roof when it exploded and sent 6ml plate in the air for over 10 seconds that was the dummest thing ive done so im looking to down scale slightly with less shrapnel. So in conclusion Im after a recipe using roughly $30 worth of sparklers to explode keeping in mind that i live in Aus so some matierals are harder to come by. thanks everybody any feedback is supported so keep the comments flowing :-)

flame igniter

Joho! i am making something similar to the "fireslinger" made by tetranite. The big difference is that mine w ill use short jolts of gasoline, that come from a perfume tester, so there will be short big flames, but i need something to ignite the small cloud of gasoline. the problem is, that it cant be a flame, or a torch, because it will be mounted on the wrist. so i will need a reliable ignition source, like a electric shock, the only problem with electricity i use, is that the sparks are too small to ignite everything, so i need bigger sparks, made by anything that will easily spark!

Worst prank EVER

So I broke a wheel off my lawnmower, no big deal, just weld it back on. How was I supposed to know that a wooden stump would break it? Anyways, since i have a shitty flux core mig welder from Harbor Freight, I decided I'd ask a friend to use their gas mig to fix it. I bring the lawn mower over, bring the welder outside, clamp the wheel bracket back on, and start the weld. All of a sudden, there's a huge ball of fire all over my mask. I immediately stop welding, and jump backwards.. yelling out, while he sits there on the ground laughing. He switched the argon with acetylene, at 10psi. Not cool. It was hilarious, but not cool.

cold explosions

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. thank you

Explosives

I am going to be filming an action film soon and I need to some explosives to use in some shots. Anybody know how to make some? I can get pottasum and all that stuff I just don't know how to make it. I also need an electric fuse so it can be set off manually not by having to wait. So if any one knows how to make that too.  I was going to use black powder but wondered if there is a better way. It will be covered with dirt to make a dirt explosion not all fiery.

Danger in separating compressor head from tank?

Wasn't sure where else to put this, I'm trying to turn an old ambulance into a shop truck and I'd like to use the stock giant O2 tanks on the side as the reservoir for pneumatic tools. How dangerous would it be to rig the compressor head somewhere else in the truck and pipe the air to the tanks? I'd of course include a pressure release valve and some sort of cup to catch moisture since these tanks wouldn't have a bottom valve (though I doubt a full on air dryer would be practical). I was hoping to use flexible tubing to run the air but I doubt that would be safe at tank pressure. Would black iron and pipe tape be enough? Am I setting myself up for a world of hurt? These tanks would be powering pneumatic tools and possibly a media blaster, thanks for any advice, Mac

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

Discharging high amounts of amperage in a very short time.

Previously I asked this question, except I wanted to build an electromagnetic dent puller. But no one gave me specific ideas or instruction of how it could be done, instead everyone told me different ways to pull the dent out, or how the metal looks.. Anyway. I have a lot of copper wire. And I have a bunch of magnets and ferrous cores, iron rods.. etc. I am wondering if I can create a very powerful burst of magnetic energy with a few winding's of copper around a ferrous core. I'm talking enough to push two very heavy objects apart, such as a television or couch... 1) Copper will be wound around about 40-60 times 2) High amperage discharge from capacitor bank 3) Possible explosion or melting wire? Thank you... again

Instructables supporting illegal activities - opinions please...

I have a few questions to the officials here in regards to supplying information to be used for illegal activities. Topics like these: https://www.instructables.com/community/Smoke-bombs-that-explode-on-contact/ https://www.instructables.com/id/How-to-Make-Fireworks/ and possible others contain information on the making of explosives. With anything from byuning over posessing to making explosives considered to be illegal and punishable by law in most modern countires I was wondering how the official point of view is on these topics? Freedom of information and so on is all good and fun but I think at some point there should be a limit. With the potential to harm or even kill people following instructions in relation to explosives I simply think topic for the help on making explosives should not be tolerated here. This only my personal opionion of course and maybe it wrong but I think supporting illegal and unlawful activities is not really necessary for a cummunity forum...

Has anyone ever done this? Will this make a massive explosion, or is there a gap?

Okay, so I have decided not to do this,but I'm just curious if anyone has done somthing simmilar to this? The design is very,very,VERY, simple,basically it is just two oxygen cylinders and two MAPP cylinders bound together with duct tape. There is an explosive device in the center (C4 or a steel pipe with blackpowder?). When the explosive device goes off, its force raptures each of the cylinders. The MAPP(fuel source, duh!) mixes with oxygen(oxidiser obviously) and heat (from the explosive device) to create one massive explosion. I'm not really going to do this, but just curious about what would happen if I did. Would it work, or is there a fault in this design? BTW- If you did or are going to try this out, please, post a video. Oh yea, and do it in the middle of nowhere where no one could get hurt,and make sure you are safe as well.

Warning to anyone who does explossives

As a former pyrotechnician, I fell like I must war people how dangerouse this shit is. Black powder is a high explosive and can be detonated with a slight impact of a feather. Flash powder is EXTREMELY DANGEROUSE, IT CAN BE DETONATED WITH OUT SPECIFIC REASONS. AMMOUNIUM NITRATE Is also another highly unstable high explosive, it can be set of even if you drop it. Gasoline is a high EXPLOSIVE, it just takes a spark to detonate. That why they are use in cars! DON"T LISTEN WHAT THESE OTHER PEOPLE SAY ABOUT GAS NOT BEING AN EXPLOSIVE, IT REALLY IS AN HIGH EXPLOSIVE, I know this because I'm an pyrotecnic. Molotov cocktails are often used in the army, they canblow up holw rooms, and if the fire on the rage hits the inside of the jar youre dead. Sparklers are another high explosive, thats why they are illigal, they can detonate and blow your whole arm off. M-80 can blow up for no specific reason, the gun powder(AKA BLACK POWDER) is extremely unstable. Match heads are also as unstable as gunpowder, it can even ignite under it's own weight. Nitrogen triiodide is also unstable. Thermite can detonate with a powerful heat and force but it can only be detonated with magnesium. Pottasium nitrate can even blow up if you just leave it there. SO, DO NOT BE DOING THESE FIREWORKS!

Cupcake Cannon

This video from Johnny Cupcakes features a steampunked pneumatic cannon firing cupcakes and test subjects in lab coats. The cannon looks awesome and the footage is shot at 700 frames a second for some nice slo-mo. It just goes to show that slo-mo explosions of pretty much anything are always fun. But if you do make such a video, please include more slo-mo explosions than people cowering in fear from cupcakes. Explosion at :57 is pretty solid, but the rest is mostly a tease. via gizmodo
