I showed my students this awesome video today about lasers and different colored balloons. We are working our way through the Light and Sound unit in class. Lasers are extremely fascinating, so we decided it would be best to see how the visible light spectrum can also be applied to a Class 4 Laser, which is the kind used in this video clip. Smarter Every Day is a YouTube channel with videos posted by Destin, a really smart guy himself.
