How to Make: a Shredder out of PVC Pipe

In this video ill be showing you how to make a Paper Shredder out of PVC Pipe. A shredder has to be stronger than what you are trying to shred, so I used the "Mohs scale" to determine if PVC would be hard enough to shred HDPE or "milk jugs". PVC is higher on the hardness scale than HDPE, but I wasn't quite sure if it would be able to shred it. So I decided to test my theory and unfortunately (at least with this set up) PVC was unable to shred HDPE. Hopefully some day I can get my hands on an Industrial Shredder!

But hopefully you enjoyed this video and learned a little about the material properties of PVC and HDPE. Thank you for watching, and if you have a project or weapon idea you would like to see me build leave a comment down below....

.... thanks! :)
FUN FACT; the Mohs scale of mineral hardness is a qualitative ordinal scale that characterizes the scratch resistance of various minerals through the ability of a harder material to scratch a softer material. It was created in 1812 by the German geologist and mineralogist Friedrich Mohs and is one of several definitions of hardness in materials science, some of which are more quantitative.
