SHARK TANK - "Episode 302" - The Sharks tear into the business idea of a Phoenix, AZ man who wants them to invest in a watch he claims provides health benefits; a stay-at-home mom from Gilbert, AZ could lose her gourmet pretzel business if she leaves the Tank without an investor; a man from Bozeman, MT with a no-tools-required furniture system hopes he can assemble a deal; and an inventor from Fullerton, CA has a small but powerful idea that could make him a millionaire. Also, Johnson Barley from Broken Arrow, OK, whose Original Man Candle did not spark a deal with the Sharks in Season Two, talks about his business since his appearance, on "Shark Tank," FRIDAY, FEBRUARY 24 (8:00-9:00 p.m., ET) on the ABC Television Network.
