TV Pixilator Light Show

This is a fun yet easy thing to make and try out with the kids.
How-2: Collect about 100 toilet paper roll tubes (the number depends on the size of your TV). You might want to ask your friends to help, it really shouldn’t take too long. You will also need a stapler and a cover. The cover can be made of a large piece of velum or any semi transparent paper or plastic (even wax paper or thin white fabric will work). I used a piece of plastic. Staple the tubes together; stapling seems to be the fastest and most secure method of connecting the tubes. Then glue or otherwise attach the cover and it’s ready. The TV Pixilator has the best light show if a bright children’s cartoon or something similar is playing.


Instead of seeing the image on the tv, you will only see spots of colored light.

Does anyone know the science behind this?

The colors going through a tube seem to mix and become one color.

    This is super neat. I wish I knew how to express the scientific explantation with this activity for our local Cub Scout pack.
