Your very own Hologram

[P4 Science and Up - Light]

You might have remembered the previous post about stenciled mirrors, and how they have small indentations on their surface to create patterns when light is shone from the back.

You can make your own hologram at home, this is a lot more hands-on, look inside your protractor set (or ask your sibling for theirs lying at home) and you can make this just by getting some acrylic at the store, or getting one from a used CD case.

What pattern do you want to make with your divider? That's up to you, nobody's asking you to reproduce the things in the video.
