Colin Furze is a very crafty man with some serious skills in the workshop and a vivid imagination when it comes to creating new ways to work with metal.
He has crafted some amazingly crazy pieces of gear over the years, like the pneumatic version of Wolverine’s claws or the world's fastest stroller, but this time around he's doing something a little less crazy- inflating welded sheet metal like a balloon:
Colin uses a process known as HydroForming to "inflate" the sheet metal, spraying a high pressure water jet into the welded pocket between the sheets of metal, thereby causing it to expand into a balloon shape.
He assures us this is totally safe as long as there isn't any air in there, but something tells me Colin inadvertently created a fun new way to launch shrapnel...
