How to create a holographic projector 2

Here is another way to create the pyramid shape you will need. Have a go at this one as well and then you will be able to decide which one is best for you.

Watch this tutorial video and have a go at drawing up, cutting out and then sticking together your own one.

We will do some learning with paper first and then when you understand the process I will give you a sheet of plastic.
We won't be using CD cases, we will use the same plastic sheets as the other projector tutorial.
