What do LCD monitors and sunglasses have in common? They both use polarisers, a filter that blocks light waves travelling in specific directions! In this session, we will make secret art using light. Learn about light polarization and how light is used in modern technologies, like LCD screens and lasers.


Preparation: LCD monitor (any computer screen works), polarizing sunglasses (Dollarama sunglasses are not polarizing), transparent tape (not “invisible tape”), transparent surface (old CD case, photo frame, Ziploc bag, or transparent Tupperware)

Expert: Irene Melgarejo Lermas, John Donohue, Kimia Mohammadi, and Sarah Meng Lim from the Institute of Quantum Computing at the University of Waterloo
