I disagree with "MRknowitall"
It's a mixing ball. It aids in mixing the paint and thinner together.
Paint base is heavy and thick. To spray out it needs to be thinned. When thinner sits in the paint, the paint will fall to the bottom and thinner will be on top.
If you spray it with out shaking.. You will get propellant, and thinner with very little or no color coming out the nozzle.
As you shake it.. The ball does 2 things. It helps mix the paint (think of paint stir stick in a qt., or gal. can of paint) and it also lets you hear when it's ready to spray.
As you 1st start shaking the can, it will feel gummy and thick on the inside. You may not hear the rattle, it could be a dull thud or no sound at all... As you keep shaking it, it will feel smooth inside the can, and the ball will move around more and start to "rattle"

The paint will drop to the bottom of the can. The makers of the paint will put a marble in the can so you can shake it and the marble will stir the paint and mix it back up with the thinner. Always shake a can until the marble is totally free before trying to paint. If you don't, only thinner will come out. Pops

there is a marble like item in the can that is there to assist in the mixing when you shake it.
spray can paint separates inside the can when it sits due to the chemicals added for the propellant, what allows the paint to come out in a spray under pressure. plus the lacquers and paint base will also separate after sitting.
its why the can says " shake well before each use ".

each and every aerosol can has 2 significant aspects: the product and the propellant. The product in a can of spray paint is in basic terms the paint itself. The propellant, in spite of the fact that, is the fabric that shoots it out of the can. The propellant is a liquefied gas. At room temperature that is a gas, in spite of the fact that that is compelled into the can at a intense rigidity, inflicting it to liquefy. pressing down on the can nozzle releases that rigidity, and various the propellant reverts to gas. This shoots the paint out. HowStuffWorks grants an dazzling diagram of the approach. So the place does that damn sound come from? A metallic ball bearing facilitates mixture, or "agitate," the product and propellant. while the two beverages are blended the two, the paint shoots out of the can nozzle in a superb mist, somewhat than in clumps.

Actualy, the marble inside does NOT help mix anything.
It's so the user knows at what point durring shaking the can the ingredients begin to mix inside.
Note: "after the mixing ball begins to rattle, continue to shake vigorously for three minutes"
It makes the consumer feel comfortable with his efforts.

Because it contains a marble or ball bearing that is used to mix the paint with the thinner so that it will spray properly !

It has a glass marble inside it, it works better to mix the paint before spraying.
