Different materials bend light differing amounts. The tendency of a material to refract light is described by its index of refraction value. Materials with higher index of refraction values are more capable of bending light as it passes from air into the material. It ends up that Pyrex glass and vegetable oil each have an index of refraction of 1.47. So what would happen if a Pyrex glass beaker was placed in a larger beaker filled with vegetable oil. Find out at this Astro Camp page. And once you've viewed the demonstration, consider trying it yourself and adding it to your repertoirre of engaging phenomenon to expose your students to.
