How do you make a smoke bomb out of a golf ball?

You need potassium nitrate and sugar. The mixture you're going to make is 3 to 2 or 5 to 3 potassium nitrate/sugar. This means, for every 3 or 5 cups of potassium nitrate, you need 2 or 3 cups of sugar. If you use equal amounts of the ingredients, the bomb will be harder to light and burn slowly. Get a pan that you don't mind getting somewhat messed up, because it might stick to it when you're done. Apply a low heat on a range to the pan, with your mixture in it. Use a spoon and continually stroke long and slowly; if you see the sugar starting to melt around the edge, lower the heat some. The mixture will melt and become a chocolate/caramel color. Continue this until its all liquefied. When it is, take it off the heat and pour it into/on aluminum foil. If you want, you can line a jello [or other] mold with foil to get a shape. Let this cool down and harden. When it is, you can peel it out of the foil. Now it's ready to light. Just use a flame to ignite the bomb, and it will burn with a purple flame, and produce smoke.
The cheap easy way, wrap a ping pong (Table Tennis) ball in tin foil, curl it at the top(used as a wick) and light it....
