Smoke bombs are sometimes referred to by different names like smoke grenades, smoke cans, or colored smoke sticks.
The color is produced by vaporizing a dye from the heat of the smoke bomb, not from burning a pigment, which always produces normal smoke. When the dye is vaporized, the pressure from combustion forces it out to produce the smoke.
It is advised not to hold them and one understands they do so at their own risk. If you choose to hold them, place your hand as low to the base as possible. They burn top to bottom and the base will be the coolest spot
