The set-up is easy; shake up the 1 liter bottle filled with water and colored beads. After the shaking, the blue and white beads mix as expected. However, when allowed to settle, strange thing start happening: the beads separate, white at the top and blue at the bottom. Then, the two separated colored beads slowly come together in the center of the liquid. Can your students figure out how it works? Can you? Great for illustrating so many concepts: solubility, density, miscibility, the salting out effect... Spontaneous order from disorder! Isn't this a violation of The Second Law?? Includes a 1-liter bottle, special density beads, salt, and directions and explanation. (Rubbing alcohol needed, but not included.)
