Pack the bowl with marbles and then tap it gently.

Explanation: In a solid particles are closely packed and only vibrate about fixed positions. Packing the bowl simulates close packing and a gentle tap simulates the small vibrations. (Removing marbles and shaking them would mimic a gas, where particles move freely.)
