If somebody never watched it, I recommend starting with the older videos, though. There isn't any dependency on the chronological order per se, but once finished with "just" making knifes from all kinds of stuff the guy gets way more esoteric over time, and some stuff he does admittedly gets rather hard to follow, since it has little to no commentary. Like instead of just using kitchen salt he'll extract it from sea water first or do something even more obscure.
Do you have a link? Search isn't producing anything useful for me. (Particularly to the jello video, but I can't find the channel either.)
