Here are some ideas for what you can do with it:
-When you're destroying your friend on COD or Gears or whatever, turn on Pure Smoke and make it seem like everything is fine, while they sit, awestruck.
-Using red smoke, do a color change from blue to red.
-Use it to age cards by performing a color change from a bike to an 1800's series. (Someone posted this on here already)
