Cut out the four joined trapezoids along the straight lines of the large circle (left). Fold along the long edges and tape the two free long edges together, to create a pyramid like shape. Open YouTube on your device and play the hologram illusion video on the QuestaconNSTC channel. Place the small end of your pyramid in the middle of your smart phone and check out the holograms (you can use Blu-tac to keep it in place). Investigate the difference between viewing your hologram in sunlight vs. a darkened room. What happens if you changed the size of the pyramid? What about the size of your screen. Further Investigation Euclidian geometry can be used to further mathematical understanding of the illusion. Check out the app (available for both Android and Apple) for a hands-on exploration. Real-world examples of this kind of optical illusion include: Pepper’s ghost illusion Teleprompters Periscopes Kaleidoscopes Mirror mazes Curriculum Links Our resources provide a framework for classroom activities and lesson plans that link to the Australian Curriculum in both the Science, and Design and Technology streams.
