Density Tubes Kit
This is a very special density column. Students drop a mixture of
blue and white beads into a tube, add alcohol, water and salt and
. . . the beads will auto-separate. But then amazingly the two bead
layers slowly move closer together to the middle of the liquid layer
. . . How can beads float in the middle of the liquid? What part
does the salt play? Can be used over and over. Original idea by
Lynn Higgins of Polymer Ambassadors.
Included: Plastic tubes with lids (6), 48 beads,
special salt, instructions & worksheets
Required: Isopropyl alcohol (20 ml per tube)
from hardware store .
