Today we will be making different colored smoke bombs.

Step 1: What You Will Need

You will need:
Potassium Nitrate
Sugar
Baking Soda
Oven
Oil Based Crayons (only these will work)

Step 2:

First add 50% potassium nitrate to a glass jar. Then 40% sugar, and 10% baking soda. Then shake until it is mixed well.

Step 3:

Add oil based crayons on stove and let them melt. Then add 5 tablespoons of the mixture we made. Stir until it is a little clumpy.

Step 4:

Then put the mixture on a piece of paper. Add a fuse and then wrap it up. Put these inside a paper towel roll.

Step 5:

Light the fuse and then voilà your smoke bombs are perfect.
<p>I made this, but despite using red oil based crayons, my smoke was gray. Any suggestions? How many oil based crayons do you use in each smoke bomb?</p>
<p>I used around 4</p>
It wont work...<br>
Does produce smoke. But no color only grey and black smoke. Ive. Tried many varaitions DOES NOT WORK
It's a unsuccessful experiment..<br>No color obtained
<p>Cool... but Is this smoke poisonous?? What can be used as fuse?</p>
<p>This is great. I have made potassium nitrate smokies before, but adding the oil based crayons is a cool addition.</p>
Good luck finding potassium nitrate
<p>You can buy Potassium Nitrate on Amazon and have it shipped to your house in 2 days. I bought 50lbs a few months ago.</p>
<p>Stump remover. Lowes or Home Depot. You can also get it for curing meat. </p>
