Have you ever seen the Batman movies and been amazed at all the gadgets the dark knight packs into his utility belt? Well I did the research and came up with a way to put you into Gotham's greatest hero's shoes by creating his famous smoke pellets!

This is an impact smoke pellet, which means when it strikes something with enough force it'll go off. How it works is by a chain reaction of different things to ignite the smoke-creating element.

Materials:

-Snappers (left over fireworks)

-Tissue paper

-Black Powder

-Magnesium Fire Starter

-Potassium Nitrate and Sugar mix (there are some instructions on how to make this online for more info)

-Penny

**OPTIONAL**

-Ping Pong Balls

-Black Spray Paint

Step 2: First Layer: Snappers

To start, cut two equal sized squares of tissue paper. Set one aside for now.

Next take 3 snappers and cut them open. Pour them all into the center of the tissue paper. Set this aside.

Step 3: Grinding the Magnesium

Take your magnesium fire starter and remove the flint rod from the magnesium (I did so by clamping a large nail in a vise and placing the flint rod on the point and hammering down gently).

The next step will be to grind this into powder. Take your file and lay it down. Then slowly and gently scrape the flint rod along the file. You can then transfer this dust onto a small sheet of paper.

Keep doing this until you get a decent sized pile (use my image as a reference). Once you have enough just sprinkle it on the layer of snappers you previously laid down.

Step 4: Black Powder and Potassium Nitrate

The next part will be adding a little more flammable fuel to your smoke pellet. Take some black powder/ gun powder (If you can't manage to find this as is, then try opening something that has it inside it. i.e. firecracker (just the black powder not the bentonite)) and sprinkle it onto the snappers and flint. It is important that you don't mix these when combining them, we need them to ignite in a specific order.

The final part will be putting a chunk of your potassium nitrate mix on top of it all.

is the smoke it produces toxic?

No gunpowder smoke is entirely safe to breathe in. It's not safe to eat though.

what do you use if you cant get gunpowder?

Just steal some shotgun shells and cut off the plastic end. Then separate the lead and gunpowder

Would this be usable inside?

It crosses my mind that I have some KNO3 laying around in my bedside cabinet (no joke).

Why are ping pong balls optional ? Aren't they mandatory ?

No actually they work when wrapped in the tissue paper just fine, the ping pong ball shell is just to give it that "Dark Knight" look. (I figured I would put that little disclaimer thing in to warn people that if they make the shell it will melt and there is no getting it back.)

Nice! If I had access to KNO3 I would probably add a little more of it with some sulfur maybe, to get more smoke.

Asamati98 (author)  Eunix5 months ago
Oh yeah good idea, and I don't know if you've already checked on this but I got mine from Walmart for $4. It was sold as "Spectracide Stump Remover".
Eunix Asamati985 months ago

Yeah, but where I live thy don't sell stump remover, and any kind of obvious chemicals that could be used in explosives are ilegal...

Asamati98 (author)  Eunix5 months ago
Oh that sucks, well if you can at least access black powder I suppose you could just use more of that... You can get a decent amount of smoke from just black powder.

Well I guess where potassium nitrate is under regulation, black powder is accessable at every gas station ;). I wonder why such explosive compounds are available in a country like the US. Oh, yeah they sell guns at wallmart too. Haha.

Nice work! Now we can all use this stuff and create smoke in the math class!!(just kidding)

Hate to break it to ya but that rod is flint and the rest is magnesium
