Smoke bombs that explode on contact Answered

my idea is as follows

have an outer layer
then inside that is a layer of a shock reactant chemical or substance
then another very thin shell
then the inner core of a regular sugar & potassium nitrate smoke bomb

the way it works is the bomb will hit the ground causing the first chemical to react then that ignites the smoke bomb which will make smoke billow out a designated hole

my example and original idea includes Nitrogen Triiodide and the regular smoke bomb mixture

ps. if you want to know how to make these things go to

I just want to note that home made explosives are illigal in any modern country these days.

The nitrogen triiodie is classified as a class A explosive in most countries I know, requiring a licence to even buy it, let alone store and use it.

I highly doubt anyone here asking for explosives is in any way qualified to handle the stuff.

Speaking from experience I can tell you that intial blasting agents like the iodide are no joke - one mistake and it is over!

There are many ways to kill yourself, why are so many people aksing for way that also endanger others??

IMHO topics like these should be deleted for good as they are nothing for people without a license and those that have one don't need an ible for it.

Knowledge is valuable. Attempting to stem any type of information because you don't think people need it is a shallow view point. Here in the US at least, we don't assume people are criminals just because they want to know how to build things that may be dangerous. People that ask questions should get answers, if the answers involve dangerous instructions that's fine as long as its made known so they can approach the project safely. Back in high school we explored nitrogen triiodide in chemistry class, and if you view the link that the author here posted, its fairly common. Instructables is not here to stifle knowledge.

instead of nitrogen triiodide, you know those fun snaps, get a box of them unwrap them and put the rocks in where the nitrogen triiodide is. You will also get a nice loud SNAP improving the effect

i need to make a exlplosve charge that goes off on impact any ideas for chemicals nmastor of chaous seems to know

use on rough concrete as follows:
Take a tennis ball
Cut a small hole in the top
Cut small pieces of ping pong balls put them in
put match heads inside
Put a wick in the hole
Glue just a bit around it to keep it in
Rub the wick with a bit of quick ignite lighter fluid like zippo
Take a circular piece of flint that is flat
Drill a hole in the middle
Put the wick through the hole put it all the way down to the ball
Super glue it
Throw it the flint will spark if you throw it right the spark will hit the wick quickly igniting it all in the matter of a second or 2

Get a tennis ball and drill a small hole in it. then break off strike anywere match heads off into it till its full. Then trow. It will either explode or just flame.

"nitrogen tri-iodide " is so sensitive you wouldn't be able to pick this up for the purpose of throwing it. Traditional fireworks "torpedoes" use a much less sensitive mixture (that it nevertheless scarily sensitive to work with.) Gravel is usually involved to amplify friction or create friction from impact. I believe firefox has a book that includes "ninja-style smoke devices."

No, "firefox" is (before it became a web browser) a company that specializes in selling pyrotechnics and fireworks chemicals and literature to hobyists.  Go here and search for Ninja:  http://www.firefox-fx.com/literature.htm
(this is the sort of "literature" that runs $0.50+ a page for xerox copies of somewhat questionable value.  Sometimes it's a useful collection of info from scattered sources with new and practical advice, sometimes it's little more than a copy of something you could have found on the net...  I have not looked at their literature in detail and can't offer an actual review.)

 NI3 is EXTREMELY sensitive.  One couldn't  even transfer it into a bomb if it were dry.

Would it be any safer or more effective with mercury fulminate instead of nitrogen triiodide?

wouldn't mercury be more dangerous if you took a breath of it, though?

if you were to some how slow down the decomposition of nitrogen triodide then it would be safer to handle, and by slowing it down it would give the smoke mixture time to ignite/begin oxidization

No it is far too dangerous to use as much NI3 as will be needed. Besides if the smoke bomb starts burning, it is a hazzard and produces less smoke. And it would be hard to transport it as well

The NI3 would explode once you touched the smokebomb or otherwise agitated it.

try mixing the nitrogen triodide with the smoke bomb solution before they harden. Or put the nitrogen triodide in the center so the smoke bomb takes up most of the impact and make it less sensitive. Does nitrogen triodide require air to burn?

Nah 2NI3 = N2 + 3I2
but I think it is way to sensitive to be used, it might explode in your hand!
Maybe Pop Pops
(the little things you throw at the ground)

the heat from the smoke bomb before it hardens would dry the nitrogen triiodide and ignite it

what if i put the nitrogen triiodide in a nut shell and glue it back together, then let the smoke bomb cool a little before encasing the nut in the it?

make a ball of the standard smoke bomb mixture and while its still hot, stick strike any where match heads all over it

Dunno if anyone else has mentioned/thought of it, but if you want an impact device, how about using the old blank cartridge/marble device? All you do is tape/glue or whatever a marble to the primer on a blank. I used to love these things I would fire them out of my sling shot, BANG! This I know is a bit primitive, but it's just to give you an idea, you can jazz it up as much as you want, but I think a blank round is the way forward on this one. Also a good smoke producer is newspaper soaked in ammonium nitrate solution, cheap to produce and light as hell. You could make some semi-decent one's with NaClO3. Don't screw around with ANTI.

A word of advice to anyone going to try to make one of these DO NOT use nitrogen triiodide (NI3). I doubt you would be able to pour NI3 in without detonation, look at this video http://www.youtube.com/watch?v=2KlAf936E90&NR=1

If you still want to try this Please use something more safe like Armstrongs mixture and you will still need to be VERY careful when putting that in the casing. Good luck!

we've long since known that this idea would not work because it is so sensitive it would go off with in your hand

You may want to think in some different ways. You could have two chemicals that are mixed on impact to create smoke, or look into the mechanical impact fuses used in early hand grenades (WW1 for reference period). You could place the smoke mixture inside an impact sensitive shell, light it, and throw it. That way the smoke would be ready when it hits, but you would have to light it before throwing.

Nitrogen Triodide wouldn't set of the smoke charge. What you can do is try using a strike any where mach head, which will ignite under the right circumstances.

The basics of this idea are "sound", however Nitrogen Triiodide is ABSOLUTLY! not the right compound for this idea! As has been mentioned a very thin coating of 50/50 Antimony Trisulfide and Potassium Chlorate might work with some smoke compounds. Surely though an in between ignition layer of a Starter Composition would be necessary. Possibly a Black Match coating would suffice.
