How to Make a Smoke Bomb

WHAT YOU NEED: 1/4 cup granulated sugar, 3 ounces saltpeter (from a drugstore or medical supply store), bowl, saucepan, spoon, paper cup, wooden matches.


1. With adult supervision, combine the sugar and saltpeter in the bowl, then heat in the saucepan over very low heat, stirring constantly, until the mixture melts into a plastic substance that resembles caramel.

2. Remove from the heat, pour into the paper cup, embed a few wooden matches, heads up, into the hardening substance, and let cool.

3. When the smoke bomb cools and hardens, peel off the paper cup, place the smoke bomb inside a clean, empty tin can or on a concrete surface (away from flammable objects or areas), light the match heads, and stand back. (Or you can simply leave the paper cup in place and light it on fire).

WHAT HAPPENS: The smoke bomb produces enough thick white smoke to fill a small room.

WHY IT WORKS: The melted sugar becomes a candy that encapsulates the saltpeter, making it easier to ignite.
