ABC's "Shark Tank" - Season Five

SHARK TANK - "Episode 502" - There's potential millions at stake when the Sharks recognize one irresistible product and a feeding frenzy ensues among all of them, including guest Shark Steve Tisch, co-owner of the New York Giants and film producer. Whose offer will win? This week's entrepreneurs include sisters from Normal, Illinois whose gourmet edible cookie dough is meant to be enjoyed unbaked; Los Angeles entrepreneurs who've created organic flavored milk that tastes like what's left in the bowl after you've eaten your favorite cereal; an IPhone app by a Georgia inventor that uses the phone's built-in hardware to make it spin hands-free for panoramic picture taking; and an interactive workout technology from an Austin, Texas entrepreneur who brings out Olympic boxer Marlen Esparza to demo his product. Plus, we follow up with the Morganville, NJ owner of Pro-NRG, a protein infused water endorsed by the NFL's Brandon Jacobs, in which Daymond John invested last season on "Shark Tank," FRIDAY, JANUARY 31 (9:00-10:00 p.m. ET) on the Disney General Entertainment Content via Getty Images Television Network.
