How To Make Homemade Smoke Grenades

This recipe will allow you to make three smoke-grenades.

1) Potassium Nitrate (60 grams)
Also called Stump Remover

2) Sugar (40 grams)

3) Baking Soda (1 tablespoon)

4) Colored Powdered Dye (1 cup)
A hobby shop will be your best bet for this.

5) 5 Playing Cards or other flimsy cardboard (Toilet Paper Tube)

6) Electrical or Duct tape

7) Cotton-Balls

8) Firework Fuses or Homemade Fuse

9) Thick Pens (3)

To start we will want to make the "shell' for our smoke-grenade. We do this by making a cylinder from one of our playing cards. Firmly tape this together. After that is done cut the other card in half and make a bottom for your cylinder by folding and taping. Next you want to securely wrap the cardboard cylinder with tape so none of your mix will ooze out while it dries.

Alternatively, you can use toilet paper tubes wrapped with aluminum foil or duct tape for the smoke bomb shells. Please note that they will be larger and produce more smoke. Is that really a bad thing though?

Now it is time to make the smoke-mix. Place the Potassium Nitrate in your pot and then add the sugar. For those of you who may have made a caramel sauce before the procedure is exactly the same. Turn your element on LOW and constantly stir.

There are two main reasons why we MUST use low heat. The first reason is that this mixture is designed to ignite with a firework fuse. I am sure you can imagine what would happen if it lit up in the pot. (If you cannot, just watch the video and see for yourself)

The second reason is that even if it did not ignite in the pot, your sugar would burn and lose its ability to slow the burning time of your Potassium Nitrate.

After about 15 minutes of slow mixing, your mixture will start to thicken and look to be the consistency of smooth peanut butter. This is the time to remove the pot from the heat.

Now you want to add the baking soda and mix it very thoroughly. Like sugar, the baking soda will slow the combustion rate of the potassium nitrate and allow for a longer burning peroid of your homemade smoke grenade.

When that step is done add the colored powered dye and mix again.

As soon as you have thoroughly mixed the powdered dye in, equally place the smoke mixture into each of the shells. Place the thick pens into the center of the mix and set aside for approximately one hour.

After the homemade smoke mix has set, remove the pens. Insert the firework fuse and gently stuff cotton into the cavity to hold the fuse in place. Stuffing it too tightly will cause the fuse to go out.

Tape up the top of the smoke-grenade and you are set.

You are now the proud owner of three new homemade smoke bombs!
