We just learned about the Water Jet Cutting.
Another way to cut metals is Plasma Cutting using a Plasma Torch.
The plasma torch shoots a fast stream of gas through a nozzle that has electricity shooting across it.
This electricity ionizes the gas, meaning that it gets the tiny electrons in the gas all super excited and the gas gets super hot!
These plasma torches are super fast at cutting metals and other materials.
