The Playground Classics Balloon Helicopter kit includes 2 latex balloons and 1 plastic propeller inside a peggable blister packet. The latex balloon attaches to the propeller and then deflates with a whistling sound, causing the helicopter to fly. A great introductory STEM toy for science teachers to use for learning about physics and motion, as well as developing kids interest in machines, flying, and engineering.
