[Scott] built a confetti canon to spice up the party. It’s pneumatic and*re-purposes*a fire extinguisher as the air tank. He had a refillable extinguisher that used water instead of chemical retardant. After emptying the water and ensuring all of the pressure had been release he swapped the hose and nozzle for a sprinkler solenoid valve. Securing the extinguisher’s actuator*lever with a pipe clamp holds the internal valve open, leaving the solenoid to control the pressure release. This way the canon can be fired electronically, or manually.
This type of solenoid valve is a popular choice with*pneumatic*canons. We suppose you could even adapt this for use as a T-shirt cannon.
