Screen Writer Looking for Explosive Chemicals


My Name is Mark Anthony Games and I am an actor and Film-maker.
I am looking for chemicals that are crystalline and react to fire by explosion. Does not have to be dramatic just enough to scare criminal gathering.

A character called Flame is obsessed with fire, so much that she researches chemical combustion to. Flames crew have set up a meeting with a criminal gang, I want something that they could have spread on the ground that will combust with either a bullet or something thrown that is on fire.

I was looking at Ammonium Permanganate ...... Suggestions Welcomed and maybe a credit in the film given ;)

I second this, just one post would have sufficed. So what exactly are you looking for, visually? There are a lot of people here that can probably help you find just what you're looking for if you describe what you have in mind. As of now, it's kind of ambiguous because first you said explosive and then you said you just wanted the ground to catch fire.

Benzoyl peroxide is used to make the spectacular fireball explosions for movie special effects.

See link here to see small scale https://www.youtube.com/watch?v=N4sfkEy4xgg

(The first half is background info, the second half is flame tests)

Yes, it's also the active ingredient in acne creams funny enough :o

Any primary explosive? Some secondary explosives are able to be set off by a bullet, just take a look at Tannerite targets, but they require quite a bit to go off, also known as the critical diameter.

Erythritol tetranitrate is a secondary explosive easily able to be prepared by any one with nitric acid/nitrate salt, sulfuric acid, and erythritol (a sugar substitute). It can be set off by a hammer blow, or a bullet. I have seen a patent about using ETN to sensitize ammonium nitrate (AN) further by addition of an amount of ETN. But the critical diameter still comes into play here, and a detonation might not be able to propagate given a "sprinkling" of it on the ground. You would need something more sensitive.

Organic peroxides are unpredictable, such as benzoyl peroxide, acetone peroxide (TATP; think terrorists), and I wouldn't want to be anywhere near it if it's sprinkled on the ground! lol

Mercury fulminate! ;-) Just don't step on it. (used in a breaking bad scene)

[Edited on 2-4-2015 by Loptr]

His name is Flame. Why not napalm? Not so much an explosion, but a lot of fire. :)

This is film/video. You do not need (or WANT!!!) a real chemical that really does the thing you wish to portray. Think "Heisenberg" walked into Tuco's lair with a REAL egg sized lump of Mercury fulminate?!

You need to be able to repeat the exact effect over and over for multiple takes, safely and precisely with a bare minimum of technical help.

Which is why such an effect would be done by a pro with something like LP gas and flame bars, not "real" solid energetic materials/pyrophorics.

I do this for a living. U2U me if you like.

Wait, for some reason I was thinking this was for a story, not an actual film.

I would have said they have pyrotechnic companies for things like that. Listen to Bert.

I withdraw what I wrote as it would likely kill you.

EDIT: I feel like an idiot right now.... :-X

Could OP make it clear wether he seeks an actual, workable SFX scheme, or a plausible sounding chemical reaction mechanism to be mentioned in the story line...

Hello all, this is for script writing purposes, will not actually be used in the filming, lol. I need to get the dialogue correct and have them tallk about the correct chemicals etc. For filming it would most likely be CGI

Also sorry about posting, did not realize they come up in the ame feed, thought they were separate feeds. My appologies

Warning! Disgruntled SFX man/weapon wrangler/armorer rant below!

-------------

Have at it, gentlemen- Important sounding and sexy, vaguely menacing buzz words- And back it up with a bit of Frankenstein lab type eye candy.

Rattle off jargon: Nitrate, nitric ester, organic peroxide, pyrophoric, pyrogenic, Goldschmidt reactions, thermite, roll out all the buzz words. Be sure to say things like detonate, high order, deflagrate, initiate, do not worry about engineering definitions.

Make sure the beakers bubble, and any liquid shown should be a really ominous color. Have a Jacob's ladder in there someplace, and some flashing lights/randomly changing digital readouts too-

Do not worry about accuracy, this is art. The "autistic director" will not care to have you heavy handedly try to teach some energetic chemistry realities at the audience, in my experience. He wants something that sounds/looks cool and dangerous, will not likely be educated in the realities of the explosive arts (Or he wouldn't be asking for your input), when every second of production work co$ts they don't have motivation to waste screen time on something so pointless to the bottom line as factual accuracy the majority of (science illiterate) viewers won't appreciate.

Sorry.

I have a few trauma induced idiosyncrasies, you DID say something about "correct" in the clarification post?

You came to the right place...

Everyone knows you buy moderator status on Amazon, not ebay!

And is the OP from April 1st? Because someone in the film industry used the word "correct" as an adjective applied to "dialogue" and "chemistry".

Make sure any labs presented in film are immaculate and full of flat screens and stuff. Also be sure to keep the computers near the funny colored/bubbling liquids Bert mentioned.

Awww. Not much to it. Pour some nitroglycerine on the ground. Soaks right in.

Produces a very nasty spot in the ground. Can actually be detonated by an errant footstep.

Sure, not always. But, often enough, that the boys think very carefully about how they dispose of their decomposing nitroglycerine.

We could say more. But, it might give some folks bad ideas. Those bad ideas might then translate into bad actions.

Actually, here is an idea as given the use of computers to alter/generate special effects, one may actually consider substances that produce a lot of smoke and little to no fire, or shock wave.

The smoke may be visually alterable to fire/smoke and sound effects modified for intensity.

This could be possibly a lot safer than having actors "playing with fire" and real high explosives (for example, just look at what happens with a cherry bomb in a bag of flour). Also, you may be able to adjust the computer generated effects without expensive and dangerous retakes. This is also in line with Bert's comment to quote:

"He wants something that sounds/looks cool and dangerous, will not likely be educated in the realities of the explosive arts (Or he wouldn't be asking for your input), when every second of production work co$ts they don't have motivation to waste screen time on something so pointless to the bottom line as factual accuracy the majority of (science illiterate) viewers won't appreciate."

Exactly!

We often use compressed air to blow "explosion" debris clouds out of various projectors, light substances such as peat moss, shredded bark, foam/balsa chunks- Then they add sound and flash in post production. Using real eplosives (especially HE's) is a lot more demanding, dangerous and expensive.

We most often use explosives for live events- Battle re-enactors, air shows, places where the fire and noise are wanted. Even then, we may use a noise effect (concussion mortar, large ground salute hung on a string, LP gas powered "crow scarer" ) next to a quiet but impressive visual effect, if the visual effect is not as loud as desired- Particularly the dust fireballs, sometimes even for gas fireballs if these are not lifted with det cord.
