Through a pitfall-ridden process that is neither for the frugal nor faint of heart, fellow Canadian Nigel Braun, of NileRed, succeeds in alloying discs of Vitreloy (a.k.a. Liquidmetal), an amorphous, glass-like metal composed of zirconium, beryllium, titanium, copper, and nickel.
This is the same material that Omega uses to infill the ceramic bezels of its timepieces. Much of the danger and all of the less-than-desirable-results Braun encountered throughout the making of these discs could have been avoided by taking a page out of Omega's playbook, using a 5-tonne heated press and water jet cutter to land on the desired form factor—but the audience is there for the danger, audacity, and perseverance. An easier, safer path to a more precise outcome would likely have made for a less engaging story arc.
Fun fact: I had the inside scoop on this video from Steve Mould months before it was published. The two of us were discussing amorphous metals over email and I'd relayed Omega's process to him, among other things. Coincidentally, he mentioned he had passed my message along to NileRed. Given the long lead times and immense amount of work involved creating videos like these, though, it wouldn't surprise me if Braun had already succeeded in completing his first of the successful amorphous metal discs by that point.
Atomic trampolines are fascinating.
