A good idea for illustrating refraction is using a laser with some sort of reflective medium in an aquarium. If you’ve never tried it before, I highly recommend Kaleidoscopic fluid… you can find it in your Boreal science supply catalog;
I add about 75-100ml of the fluid to a small aquarium full of water, and then [...]
