Lifty and Skoop have gotten together to play with their quadrocopter, but Skoop's forgotten to charge the batteries. What should they do? Lea thinks they should build a hot air balloon. It doesn't need batteries or electricity to fly. Leo brings the parts, and the group gather round and decorate the balloon. Time to make it fly. The quadrocopter finishes charging just in time. While Leo and Skoop go flying, Lifty's going to take beautiful photographs with the help of his quadrocopter.
