‘I have a PhD in mechanical engineering and I learned nothing new about folding from this video but I’ve watched it 40 times for quality assurance purposes.’ That’s a real comment with 87,000 likes. Other highlights include a man explaining in 600 words why the reverse inside fold used at the 0:31 mark is ‘technically superior to traditional methods’ despite admitting he had never heard of origami before Tuesday.
