Certain tricks of the mind or illusions can be quite mysterious; this helps magicians appear to defy natural forces and do the impossible! Students in this Saturday STEM will become Magician Apprentices who will explore some 3D optical illusions, frequently used by Magicians. Participants will build a device that will allow them to perform a floating object trick right from their very own hands! Additionally, students will build and test a device that allows them to create and visualize holographic-like images. Along the way, students will discover some of the underlying STEM principles which allow these illusions to exist!
