With more than 30 locations located around the world, the 5,000-sq-foot Museum will feature optical illusions, holograms, stereograms, and immersive experiences. The Philadelphia Museums will consist of many popular exhibits found at other locations. However, the Philly location will incorporate a few local themed displays. For instance, a house based on a historic Elfreth’s Alley design and an “Upside Down Room” based on the concept of a Philly diner. The Museum of Illusions is expected to open sometime in November and the admission fee is expected to be around $20 for adults and $15 for children.
