Fog machines and smoke machines are all fine and good, but they tend to be cumbersome, and they have a knack for lingering long after you use them. If you happen to be sharing the stage with other performers putting on their sets before or after yours, a smoke machine might not be feasible to set up and takedown. Not to mention getting you labeled as “That Guy” who leaves a smoke-fouled stage for the next performer. That’s where this Diffusion – Cloud In A Can comes in handy!
