This is completely ridiculous, like those TV commercials where some clumsy person nearly severs their own hand with a knife because they're not using the infomercial's special chopping tool. The guy making pancakes was especially egregious. His friends were laughing at his stupidity, and he likely hammed up the remainder of his "performance"... who swings an egg by half a meter to crack the shell on the edge of a bowl? It's as if they went out of their way to find people who have absolutely abysmal proprioception and watch them bumble along even more as their inability to perceive the world they live in gets magnified.
Next on the front page of HN - "Living with weight". A video showing "experiment" where people are going on with their daily lives, except they have 4 bricks strapped to their face and it's hard for them to keep head straight, they are laughed at, one is fired from office. At the end, text "Living with weight is hard. Samsung New Phone. Weights 10g less than iPhone."
