Make your own 3d hologram projector – How and Why?

What you will need:

  • Plain paper
  • Pyramid template
  • Piece of acetate or CD case
  • Black marker pen
  • Scissors
  • Sticky tape
  • Smartphone with hologram app

How?

Using the marker pen trace the template onto the acetate and carefully cut out. Score and fold along the red lines. Tape the free ends together to form a pyramid. Search online for ‘hologram videos’. You Tube has lots of good ones. Place the pyramid in the centre of the phone screen. Switch the lights off, play the video and view the hologram from the side as shown in the diagram below. Enjoy!

Why?

4 distorted images of a 3d model are displayed on the phone screen. These are reflected on the four sides of the pyramid. When the pyramid is viewed straight on, the 4 separate reflections come together to produce one 3d image.
