Regardless of how annoying he might be, David Blaine’s TEDMED talk on how he set the world record for holding his breath underwater for 17 minutes is pretty phenomenal. Definitely interesting to see the different ways he thought of to do it as an illusion, using various technological methods and DIY gadgets, before finally deciding that he would do it for real. This one is definitely worth watching, and also worth not trying at home. It’s kind of ridiculous.
