Recent advances have brought us closer than ever to mastering one of the holy grails of science: invisibility. With an Invisibility Kit and this hands-on STEM activity uses a simple four lens set-up to get a close look at using light’s refractive property to create regions of invisibility. We can also explore the math that makes it work, and how invisibility is useful to Muggles.
