I'm Mechanical Engineer and YouTuber Mark Rober. Recently featured on Reddit for creating the 'Courtesy Honk' Car Horn and Automatic Bullseye Dartboard. Been making monthly videos for 5 years and I just hit 2M subs! AMA!!
Hey guys!! I still work a 'real day job' (currently home for lunch) but YouTube has been such a cool creative outlet for me for the past 5 years. Getting people pumped about science and education is something I'm passionate about. I genuinely can't process that 2M have hit the subscribe button. Ask me anything... and I mean ANYTHING... that sounds creepy... just ask my anything.
tl;dr of me: I have a Masters in Mechanical Engineering. I worked at NASA for 9 years (7 of which were spent on the Curiosity Rover). I started a Halloween costume company from one of my videos and then sold it to some dudes in the UK and worked for them for 2 years at which point I was offered an opportunity to work for a large tech company in the Bay Area in their product formulation area which I do now.
YouTube has allowed me to fill a pool with 25M Orbeez to investigate buoyancy, earn 2 Guinness World Records (Largest Nerf gun and Largest Super Soaker), go on Jimmy Kimmel 4 times, travel to a bunch of cool places and interact with a bunch of cool people.
UPDATE That's all for now! I'm taking ma boy camping. That was cool. I'll hop back on tomorrow afternoon and answer any additional questions that came in!
