Potential Study #1

Say that you have a large jar of trail mix: peanuts, sunflower seeds, raisins, and m&m's. If you shake it, won't the heavier objects (peanuts) settle at the bottom and the lighter objects (sunflower seeds) rise to the top? Or will the sunflower seeds fall to the bottom because they're small?

No matter which direction it would take, I'd also like to track one individual seed on its journey and see how it ends up where it does.
