This Is Mark Rober

In his quest to understand terminal velocity, Mark carefully studies some furry friends before jumping out of an airplane to become a flying human squirrel.

Which pool would you prefer to dive into? One filled with 25 million Orbeez, one filled with liquid sand or one filled with jello? Luckily, Mark takes us on a journey in all three, before unveiling a never-before-seen, top-secret blaster.

Mark dives into the most absurdly scaled-up toys he's ever made: the world's largest Nerf blaster, the world's largest Super Soaker and a snowball machine gun. But has he met his match with a brand new toy that ends with a bullseye-induced fireball?

Mark gets sporty in a field-goal kicking contest with his mechanical creation, shows off a rocket-powered golf club and perfects the art of rock skipping -- but not before his field-goal robot smashes more than just a football!
