Mario beat me to it, but I was going to say that if you can't get different pitches by using different sized eggs, the size of the particles inside might yield a difference in pitch.

Rice should sound higher pitched than beans, which should be higher pitched than gravel.

Or not. I don't have a plastic egg to test this theory. ;-)
