Can paper cut wood? It couldn’t possibly, right? Wrong. It turns out a single sheet of paper can cut through wood, and it’s all about adding some motion.
On its own, a piece of paper is weak and ineffectual. However, insert it into a circular saw, and that same piece of paper is transformed into a solid cutting tool.
The motion makes the paper harder and less prone to tearing. At which point it can easily cut through other paper, and even have a go at some real wood.
The lack of serrated edges mean the paper is essentially cutting through the wood using friction, hence the burns on the wood after the fact. Which makes it even more amazing to watch, quite frankly.
