These semicircular plastic cells with clearly demarcated measurements are perfect for observing the refractive properties of different liquids such as water, oil, alcohol, or other transparent liquids. The refraction cups are made of a clear, durable plastic and are economically priced for bulk classroom purchases. The inside of the cup is printed with clear and precise degree measurements, from 0-180, in both directions, so that you can produce the most accurate results possible from your refraction experiments.
