It sounds like the nozzle was clogged. Inside each can of Rust-Oleum Specialty Glitter Spray is a dip tube that pulls the paint from the bottom of the can to the tip. If the pigment in the paint is too big or if there's not enough pressure behind it, it can get stuck in the tube or tip and the paint won't spray. Try turning the can upside down and spraying for a few seconds. If the clog is in the tip, soaking it in mineral spirits should clear it out. Make sure you are also shaking the can thoroughly before each use to prevent settling of the glitter.
