Description
You show two empty bowls that are exactly the same size. Fill one with rice to the brim. Place the other on top so that the openings face each other. Shake the bowls and lift the top one off. You now have twice as much rice – yes, the rice will spill over the edge. Wipe off the rice and place the second bowl on top. Once shaken, the rice has turned into water, which you can elegantly pour from one bowl to the other – the bowls can of course be given for examination.
