Amaze students with a discrepant event using cooking oil and glass. A test tube immersed in cooking oil seemingly disappears as the tube is filled with cooking oil. Introduce scientific observation, properties of light, reflection, and refraction as students try to explain this modern-day "cloaking device." Kit materials may be used to perform the demonstration multiple times. Includes instructions.
