Too cool!-Colleen Too cool!-Colleen Science Fair Projects Science Lessons Science Experiment… One experiment I always wanted to try was using a stream of water like a fiber optic cable to bend light. This experiment demonstrates a total internal reflection and shows the principle of optical fibres. Watching the original light refraction experiment on YouTube will give you a great look at what’s involved in this activity. The Mirror Method. Similar to our Optical Illusion science experiment, light experiments also rely on what our eyes see. For further information, consult your state’s Science Safety Handbook.
