Maybe the following would work. Make a gradient index like ours (you gave =
the link below) using gelatin instead of plain water. Make a second one. =
Pop the two out of their molds and sandwich them together with their high-c=

Hi Tap ers
The Exploratorium Explainers are working with NOAA and want to build an opt=

I want to build a jello based gradient index (GRIN) optical pathway that wi=

I showed them the one where I layer water (doped with milk) over corn syrup=
(doped with milk) and leave it for a day to allow a gradient to form. But =
they want the gradient at both sides of a channel not just at the top.
I found this site on line but the gradient looks a bit too gentle.
Anyone have ideas about or experience making a stronger gradient?
Or do I just make a very long tube of GRIN jello.
