What do water and knives have in common? Well, if fired at a high enough speed, water can cut just like a knife.
The water jet cutter uses a high pressure water jet to force water through a diamond-shaped nozzle that is a mere 0.004 inches in diameter. Paprima, the Canadian company that makes the cutter, says that it shoots water at three times the speed of sound and can make a clean cut through hard and soft materials.
"Water-jet technology is an excellent choice when processing viscous, gelatinous and multi-ingredient food products such as baked goods (snack bars), and confectionary (fruit extrusions)," Paprima said in a statement.
And the benefits go beyond cutting. DISCOVER magazine's Discoblog reports: "It also, as long as the water is clean, does not leave bacteria on them, which is a downside of using a metal knife to process sliced foods."
The cutter has been proven to work on fish, meat, fruits, vegetables and pastries. Note: It can also cut fingers. But you might not have to worry about that because the cutter is not commercially available.
