Great for illustrating so many concepts: solubility, density, miscibility, the salting out effect.

When the 1L bottle is shaken, blue and white beads mix as expected. However, when allowed to settle, 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. How often do you see something floating in the middle of the liquid? To be used with alcohol (Rubbing alcohol not included.)

What’s Included:

  • Bottle with beads
CHOKING HAZARD! Small parts. Not for children under 3 yrs.
Grade Level 5, 6, 7, 8, 9, 10, 11, 12
