Unfold the hologram device into a pyramid shape. Peel off protective plastic from both sides of the pyramid.
Wedge the double-sided suction cup into the center hole of the pyramid so that one cup is on each side.
Turn the brightness all the way up on your phone. Search for “Hologram Pyramid” on YouTube, or just open this link on your phone. Make sure the video is full screen/in landscape orientation. https://www.youtube.com/watch?v=TcUHV6bHOeg&t=50s
Make sure you are in a dark/dimly lit room. Begin playing the video. Stick the suction cup onto the center of the phone screen. Hold the phone flat with the screen facing upwards at eye level. You will see a magical hologram floating above your phone inside the plastic pyramid!
