Brody is quite the exceptional kid. Not only is he a survivor of blood cancer, but he used his one Make-A-Wish to make sure another kid with cancer got the ATV he always wanted. Mark Rober was so moved by this story that he decided to throw Brody the most epic pool party ever! Not only was this a party full of friends, family, water slides, an Orbeez pool, and trash can rockets, it also included a world record. Mark, Brody, and friends were on hand to witness the eruption of the world's largest elephant toothpaste volcano!
