If you ever find yourself with 100 ping pong balls, a bunch of aluminum foil and some cannon fuse then you can build this totally pointless ping pong ball smoke bomb.

Better yet, just watch CrazyRussianHacker do it on YouTube because "Safety is his number one priority".

Even though we don't recommend it, if you do find yourself gathering the needed supplies, then make sure you make safety your number one priority, too.
