Steve Spangler Science: Smoke Bomb Smoke Ring Launcher

With few simple tools, you can launch puff-perfect smoke rings from a homemade vortex generator.

You’ve seen ways to launch tiny smoke rings with small, plastic cups and shoot huge rings from a giant smoke ring launcher made out of a trash can. Here’s a way you can build a medium version with simple materials. Combine an empty plastic container with a smoke bomb and you’ll be creating swirling vortexes of smoke in a few minutes. Besides the awesome smoke rings you’ll make, you’ll gain a better understanding of how a vortex generator works.
