Paint the entire ceiling black with a paint roller, using a flat-finish paint. You might need to apply a second coat to get a truly even color.
Choose the locations for your shooting stars. Spacing them out by at least a few feet will heighten the effect.
Use an artist's paintbrush to place a dab of yellow glow-in-the-dark paint where you want the shooting star to be located.
Pull the paint brush back in a straight line so that the glow-in-the-dark paint gets continuously lighter as you move away from the tip. This creates the illusion of a shooting star. Be sure the tip of the shooting star is the most prominent point.
Add other stars all across the ceiling with single dabs of glow-in-the-dark paint. Make the surrounding stars varying levels of prominence so that some appear lighter -- or farther away -- than others. You can mix white paint with the yellow paint to achieve the lighter effect.
