3d hologram projector working model for school science project exhibition with explanation

by

Introduction:

In this project, we will create a simple 3D hologram projector using cardboard, transparent plastic paper, and a mobile phone. This model will demonstrate the concept of creating three-dimensional images using a pyramid-shaped structure and a specially designed video.

Materials Needed:

  1. Cardboard
  2. Transparent plastic sheet (clear plastic or CD jewel case cover)
  3. Mobile phone
  4. Ruler
  5. Pen or pencil
  6. Craft knife or scissors
  7. Adhesive (glue or double-sided tape)

Step-by-Step Explanation:

  1. Preparing the Base:
    • Cut a square piece of cardboard for the base of the hologram projector.
    • Place the mobile phone on the base and mark its outline.
  2. Creating the Pyramid Structure:
    • Measure and cut four cardboard triangles with equal sides. These triangles will form the pyramid sides.
    • Attach the triangles to each side of the outlined square on the base. The triangles should slant upwards, meeting at a point.
  3. Assembling the Transparent Top:
    • Cut a square piece of the transparent plastic sheet that matches the size of the top of the pyramid.
    • Attach the transparent plastic sheet to the top of the pyramid structure using adhesive. This forms the top surface of the hologram projector.
  4. Creating the Hologram Video:
    • Search for 3D hologram videos on platforms like YouTube. These videos are specifically designed to create the illusion of a 3D image when projected through the pyramid structure.
  5. Playing the Hologram Video:
    • Place your mobile phone in the center of the pyramid structure, with the screen facing upwards.
    • Start playing the chosen 3D hologram video on your mobile phone.

Demonstrating the 3D Hologram:

  • As the hologram video plays on your mobile phone, the light from the screen is reflected and refracted by the pyramid structure, creating the illusion of a three-dimensional image floating above the projector.

Conclusion:

By building the 3D hologram projector working model, you’ve demonstrated how a pyramid-shaped structure can be used to create a captivating illusion of three-dimensional images. This project showcases the concept of holography and how it can be applied in simple DIY projects.
