@jonr7870 They're Water Gel Crystals, which come in different shapes and can be found at a website called Teachersource. The full demo can be found in Prof. Shakhashiri's new book, Chemical Demonstrations Volume 5, which can be found at the University of Wisconsin Press site, or on Teachersource. Glad to hear you're going to be doing this with your students!

What is the gel used for the second refraction demo? I want to use it in my class.
