Hydroforming Cube with a Pressure Washer

How to use DIY Hydroforming to inflate steel cubes from flat to 3D. The first experiment attempts to mimic an expanding paper origami cube, but proved to be much trickier to achieve using sheet steel due to the large force required to unfold correctly. I may try this again, inspired by how the MythBusters managed to make an inflatable cube/balloon from sheets of lead.
