Just in time for Shark Week, marine biologist and shark diving expert Luke Tipple swims up to the YH Studio to give us the scoop on his 'Hunger Games'-inspired reality TV competition series, "Capture"! Luke explains the premise of the show, plus he tells us about the first time he dove with sharks without a safety cage, and he also advises us on what we should do in the event of a freak Sharknado! Hosted by Nikki Novak (@nikkinovak).
