Save money with this DIY physics project, by making authentic scientific tools with recycled materials.
Step 1: Required materials:
In this project I'm gonna show you how to make your own spectroscope, for under 5 bucks.
Here is what you need:
a carton or pvc tube, I'm using a toilet paper tube myself.
