Why do/did Spray Cans Have a Marble?

George Daniels, in his book Make Your Own Monstrosities with Tooth and Nail, gives simple instructions for painting your living room. Light the fire in the fireplace, and throw several cansful of your selected color into the fire, and the resulting explosion will coat the room and everything in it with paint. All you need to finish the job is an old mop. There are no brushes to clean, no rollers to wash, no glass in the windows.

It’s not an aerosol, but the same idea.
