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.
Step 1: Materials
-Snappers (left over fireworks)
-Magnesium Fire Starter
-Potassium Nitrate and Sugar mix (there are some instructions on how to make this online for more info)
-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
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 final part will be putting a chunk of your potassium nitrate mix on top of it all.
Step 5: Wrapping
Then take your other tissue square and place the penny in the center. Then put the wrapped item on top of the penny and wrap it all up.
You can now tape the top and trim it so it is smaller and won't unravel.
You have now completed your very own impact smoke pellet! Keep reading to see how to make it look like one of the Dark Knight's gadgets!
Step 6: **OPTIONAL** Ping Pong Housing
First you'll need to take a ping pong ball and cut along the seal. Then depending on what color you want, spray paint the two halves.
When that's done drying, hot glue (or tape) the impact smoke pellet into one half of the ping pong ball.
To seal it up just put a ring of hot glue around the area you cut and put the other half on top of it. You may also want to clean it up a bit and reinforce the seal.
When the hot glue is all done drying, your Batman Smoke pellet is complete and ready to tested!
Step 7: How It Works
1) The penny acts a flat surface for the snappers to hit and activate.
2) The snappers then activate due a coating surrounding the rocks that creates a small spark.
3) That spark then ignites the flint powder which makes the spark a little bigger.
4) Then the spark given off by the flint is enough to ignite the black powder.
5) The flame created by the black powder is big enough and strong enough to then burn the potassium nitrate which smokes quite a bit.
This chain reaction of elements is a little lengthy but all together a pretty simple concept. Now that you know Batman's secret to his famous smoke pellets, its time to put it in action.
Step 8: Testing It Out
First what you need to do is go out and find a band of criminals somewhere that you can disappear from... or maybe just go outside! Then to make it smoke just throw it down! (make sure you throw it right-side up, if you put it on a table or the ground it should automatically position itself that way because it is attached to one side) You will hear the casing pop open and then the smoke will follow. For added effect get a crowd and stand by a corner, then throw it down and run behind the corner so it looks like you've disappeared! (This may only fool the young ones though)
Congratulations on making your very own gadget worthy of the Dark Knight's utility belt! So all that's left to do is to go out and protect the streets of Gotham!
**NOTE: The potassium nitrate will burn, so be cautious and never throw this at anyone. Also it will leave your ping pong housing a pile of melted plastic so if you don't want to take all the time making it I suggest leaving that step out, it is purely aesthetic.**
