IT'S A HOLIDAY-THEMED EPISODE IN THE TANK AS ENTREPRENEURS CONVINCE THE TOUGH SHARKS TO GET INTO THE HOLIDAY SPIRIT, ON ABC'S "SHARK TANK"

"Episode 512" - A man from Lubbock, TX believes his colorful, magnetic light strands hold the solution to one of the holiday's biggest headaches; a man from San Diego, CA pitches his Christmaskah item for interfaith families that bridges the gap between "Ho, ho, ho," and "Dreidel, dreidel, dreidel;" and a business duo from San Diego presents a fashion show highlighting their fun, witty take on the traditional Christmas sweater of the past. Also, a model and hairstylist say there is nothing fake in wanting to make a real deal with their luxurious clip-in hair extensions. The holidays have already taken off for Marine Corps aviation officer Major Robert Dyer, a highly decorated combat veteran of Iraq and Afghanistan, with RuckPack, his energy and nutritional supplement designed and tested by active duty military personnel, which Kevin O'Leary and Robert Herjavec invested in during Season 4, on "Shark Tank," FRIDAY, DECEMBER 13 (9:00-10:01 p.m., ET) on the ABC Television Network.
