How To Make A Smoke Pull-Ring Grenade

How to Make a Real Smoke Grenade – the one hour method

One of the best methods to create a smoke grenade is basically a mixture of potassium nitrate and sugar. The former ingredient is also known as saltpeter and usually it’s not available for purchase. But you may use Spectracide Stump Remover which consists mostly of saltpeter. It works just fine!

You’ll need:

  • 60g of Saltpeter (sometimes found in Garden Shops) or Spectracide Stump Remover(availabe on Amazon) ;
  • 40g of Sugar
  • One spoon of Baking Soda
  • 3 large spoons Organic Powdered Dye (found at Hobby Shops) – for color smoke bomb;
  • Card Tube (or toilet paper tube, soda can)
  • Pen
  • Firework fuse or make your own fuse
  • Duct Tape

 

The mix will be placed in a soda can that you have to cut in half. In order to create a good mix for this smoke grenade, add two parts of sugar to three parts of saltpeter. Cook these two ingredients and mix them constantly until they create a golden paste that is rather gooey. Stop the fire now as if you keep the mix on fire any longer, you risk igniting it and you don’t want a smoke grenade in your kitchen.

While the mix is still warm and malleable, pour it into the soda can that you cut earlier. You will have half of a soda can filled with a gooey substance that will soon solidify. This is the moment when you need to put a fuse into the mix. Place a thick string about an inch inside the mix and leave at least two inches outside. Then, you can either refrigerate or freeze the soda can or wait for it to cool down and harden naturally. It will take about 20 minutes for the mixture to be solid and then, you will be able to light it on fire.

However: this is a much more powerful smoke grenade than the next one and you should ignite it only in open environments. Also, try to avoid lighting it near your neighbor’s house as he or she might not be eager to be surrounded by a thick layer of smoke. This smoke grenade is unlikely to put something on fire, because it is contained in a soda can, but you should not leave it unattended, either.

How to upgrade your smoke grenade?

1. Add a pull ring fuse:

2. Add more colors: if you want to upgrade your smoke grenade you can also add more colors. This is not something that can be done with the second type of smoke bomb, as you cannot add color into that solid mix of elements. In order to do this, you can simply use organic food color. Note that you’ll have the best (coloring) results using other formulas (point 3):

3. Use other recipes: some chemicals may not be readily available unless you have access to a chemistry lab, but it’s worth knowing how it’s done. The ingredients are sifted together and ignited to produce the smoke.

How to Make a Smoke Bomb – the 10 minutes method (to entertain your kids)

These smoke grenades, also known as smoke bombs, are probably something you did as a child. If not, at least you had a friend who did them.

Depending on the size of the smoke bomb, you might want to add any amount of ping pong balls you want.

However, a medium sized smoke grenade is perfect with about 5 balls. Cut all the ping pong balls. This will take you about 10 minutes. Each piece of the ball should have about half-inch in order to be packed with ease into the tinfoil later. Large shards will not burn properly and they might also puncture the tinfoil too. The alternative is to smash the balls and then rip them apart by hand, but this is much more tedious and you could also get a cut, as plastic can also be quite sharp.

Now you can either place them in another ping pong ball that was previously pierced in order for the shards to be placed inside, or you can directly wrap all of the small bits into tinfoil. If you want a single exit point for the smoke, use a pencil as you wrap the shards. Place it in the tinfoil and wrap the foil around it. Then, take the pencil out and you will have a miniature chimney from which the smoke will come out. The final step that you need to perform during this process is to light up the smoke grenade. Light the part with the ping pong ball shards until you see smoke coming out of the “chimney” and then step back.
