Osmosis

Type of activity: demo

Activity code: H-008

Description:

Demonstrates diffusion and osmosis through 'semi-permeable' separator. 1) Start by sloshing the box sideways to separate bearings from glass beads. 2) Height of bearings should be similar to height of glass beads. 3) Shake box horizontally (best along table-top) for 10 seconds. 4) Observe the effects of the bearings 'diffusing' into the glass beads.
