Week 8, The 100th Episode: Storm Stoppers, Pipsnacks, Squatty Potty, Heidi Ho

The Sharks celebrate 100 episodes with a look back at their favorite memories, plus they reveal why they participate on the show, as well as take part in a cake-cutting ceremony and a champagne toast. Also: a mother and son who are concerned with healthy bowels; a plywood alternative for storm protection; organic mini-popcorn created by siblings from Brooklyn; a dairy-free line of plant-based cheeses; and an update on the Living Christmas Company invested in by Mark Cuban during Season 5.
