A family with kids created a giant ball pit in their backyard pool by filling it with 15,000 ball pit balls. They also added four large Super Wubble Bubbles filled with water and air, which floated on the surface. The kids and their dad, Carl, jumped off a trampoline into the pool, doing tricks and stunts through the ball pit balls and Wubble Bubbles. Later, Carl tried to swim underwater from one side of the pool to the other without taking a breath, but didn't quite make it. The family then worked together to create a giant wave pool effect by moving the water and ball pit balls in unison, creating waves and having fun.
