Building a LEGO Hologram Table: A Fun Science Project

Building a LEGO Hologram Table

Have you ever seen a hologram and thought it was magic? While holograms are created using science, they can certainly seem like magic! In this blog post, we’ll be exploring how to build your own LEGO hologram table. This project combines creativity with science, and it’s a great way to learn about how holograms work.

What is a Hologram?

A hologram is a three-dimensional image created by using lasers to record and recreate the light waves that are reflected from an object. When you look at a hologram, it appears as if the object is actually there, even though it’s just an image. Holograms are used in a variety of applications, including security features on credit cards, entertainment, and even medical imaging.

Why Use LEGO?

LEGO bricks are a versatile building material that can be used to create all sorts of things, including our hologram table. LEGO bricks are easy to work with, and they are durable enough to hold the weight of the table. They are also readily available and affordable. The LEGO pieces can be easily assembled and disassembled, making it easy to experiment with different designs and adjust the table as needed.

Building the LEGO Hologram Table

To build your LEGO hologram table, you will need the following materials:

  • LEGO bricks
  • A small, flat object (like a coin or a small toy)
  • A smartphone or tablet
  • A clear plastic sheet or a piece of glass
  • A small piece of cardboard or foam board
  • A flashlight


  1. Build the Table Base: Use LEGO bricks to build a sturdy rectangular base for your hologram table. The base should be large enough to accommodate your object and your smartphone or tablet.
  2. Create a Platform: Build a small platform on top of the base. This platform will hold the object that you want to create a hologram of. You can use LEGO bricks to make a simple platform, or you can get creative and build something more elaborate.
  3. Add a Support Structure: Build a support structure that will hold your clear plastic sheet or piece of glass above the platform. This structure should be tall enough to allow for enough space between the object and the plastic sheet.
  4. Secure the Plastic Sheet: Place the clear plastic sheet or piece of glass on top of the support structure. Make sure it is securely in place. The goal is to have the sheet sit at a slight angle.
  5. Position Your Object: Place your object on the platform, directly below the plastic sheet. The object should be centered on the platform.
  6. Set Up Your Smartphone: Place your smartphone or tablet on the table, so that the screen is facing the object. We will use a holographic app on your smartphone to project the image.
  7. Find a Hologram App: There are many free hologram apps available for both Android and iOS devices. These apps will project images on your screen that will appear to be 3D when reflected on the plastic sheet.
  8. Test and Adjust: Once you have everything set up, turn on the flashlight and shine it on the object from below. You should see a reflection of the object in the plastic sheet. Adjust the angle of the plastic sheet, the position of the object, and the angle of the flashlight until you get a clear image of the object. You can also experiment with different hologram apps to see which ones create the best effects.

Tips for Success

  • Use a small, flat object for your hologram. This will make it easier to get a clear image.
  • Make sure the plastic sheet is clean and free of dust or smudges.
  • Use a strong flashlight to create a bright reflection.
  • Experiment with different hologram apps to find one that you like.
  • Be patient! It may take a few tries to get the hologram working properly.


Building a LEGO hologram table is a fun and rewarding project. It’s a great way to learn about how holograms work, and it’s a great way to unleash your creativity.
