YouTuber The Action Lab is a prolific science expert who has brought us many cool videos such as this one where he made a laser microscope using just a drop of water or this one where he made a black mirror. Now, he is back with an interesting and entertaining video where he explains how shifty or color-changing glass works.
He starts by showing us examples of three types of this glass. He takes light yellow, dark yellow, and blue pieces of glass and he changes his lightbulb from a halogen one to a compact fluorescent one.
Immediately, the pieces of glass turn pink, orange, and violet. How does such an extreme change occur?
