Inventor Demonstrates How to Fill Up Metal Sheets Like a Balloon With a Modified Pressure Washer

British inventor Colin Furze demonstrates how to transform sheets of metal through hydroforming by using a pressure washer to fill them up like a water balloon. Furze makes all sorts of interesting shapes, including a cone used to amplify the engine sounds of a riding mower and a square resembling a small metal pillow.
