I'm working on a high school musical production and would like to incorporate some streamers or confetti into the finale. I'm just starting to research some air powered cannons. I'm not really sure how much I would need.
The show is happening in a commons/cafeteria/stage space that seats approximately 400 with about 20+ foot ceilings. The stage is 42' wide.
I'm not sure if I would need something more than this for the effect or not:
Or would I be better off looking at renting something? I'd appreciate any and all thoughts.
