This is for my legacy project in Chem 4011.  The pictures below show the diffusion of dye through gel and water.  Three different graduated cylinders were used:  one with gel and dye with water on top, one with gel and dye with gel on top and one with plane gel and dye on top.  So far we have observed the graduated cylinders for one and a half months.  The dye has dispersed throughout all of the water in the gel/water and is slowly darkening as more dye leaves the gel.
