Description

Classic Whistle Balloon Helicopter s Classroom Set Includes 12 Balloon Helicopters and Air Pump This classroom set of balloon helicopters includes everything you need to have a high flying, balloon powered good time! Inflate the balloon with the included air pump and attach it to the propeller. Watch it take off to heights up to 30"!!! This classroom set can be used to teach about Newton's Third Law - "To every action there is always an equal and opposite reaction." Teachers should note that Newton's Third Law has to be applied twice in order to explain the upward motion of the helicopter. The exhausted gases coming from the inflated balloon force the fan to rotate, driving the air downward. The reaction of wind, in turn, provides the lifting force for the helicopter. Balloons vary in color. Helicopters arrive unassembled in a resealable bag. Helicopter has a 10" diameter when assembled. Can be reused. CHOKING HAZARD – Children under 8 yrs. can choke or suffocate on uninflated or broken balloons. Adult supervision required. Keep uninflated balloons from children. Discard broken balloons at once. Ages 8 & up
