A CAR THAT RUNS ON COMPRESSED AIR, DIET SNACK BARS, SNAP IN AND OUT EYEGLASSES AND FRAMES, AN AMAZING FISHING LURE AND AN ENTREPRENEUR DRIVEN TO TEARS, ON THIS WEEK'S "SHARK TANK"

Famed crooner Pat Boone Helps Pitch the Eco-Friendly Car

"Episode 626" - The Sharks take no prisoners, driving one entrepreneur to tears and grilling another: "Are you here to get exposure or to get exposed?" This week, a man from Brattleboro, VT joins singer Pat Boone to pitch a new eco-friendly car that they claim is superior to electric vehicles because it runs on compressed air; a super-fit mother of three from Ft. Collins, CO touts the benefits of her snack bars connected to a popular diet; a fisherman who holds the world record for biggest striped bass ever caught tries to net a Shark's investment in his unique lure that helped him make that catch; and two men from Cincinnati, OH provide customers with sets of glasses and frames that are interchangeable and reasonably priced. And a follow-up story on Heidi Ho Organics in which Lori Greiner invested earlier this season on "Shark Tank," FRIDAY, MAY 1 (8:00-9:00 p.m., ET) on the ABC Television Network.
