    Product Description


    1.  Show parallel rays of light formed as laser light passes through beam splitter and tank of water.
    2.  Hold convex cell filled w/ air in the water tank.  Align it so the rays pass through convex sides of cell.  Notice the divergence of rays.
    3.  Repeat with the concave cell.  Notice the convergence of the rays.

    Option:  The expected convex / concave affects associated w/ glass lenses can be shown by filling each cell w/ water & passing laser through it.
