Your students will be enthralled with Newtons laws of motion and the principles of air and flight using these balloon helicopters. Science has never been so fun! Your students will love blowing up the balloon, tossing the copter up into the air and then watching it soar! Up to two stories high with new balloons. Wow! They also get to practice some basic construction skills by putting the helicopter together themselves. Age: 7 + What you get25 Balloon helicopter packs.Each simple plastic pack contains: three blades, blade connector, hub, and two balloons.How does it work?The first thing to do is assemble the helicopter. It is easy to put together following the pictures on the back of the pack. Then its time for the real fun. Blow up the balloon, pinch it shut and attach the hub on the end of the balloon to the blade assembly. The gases escaping from the balloon force the blades to rotate. The rotating blades, in turn, drive the air downward to provide lift and propel the helicopter high into the air. Awesome! Newtons Third Law needs to be applied twice in order to explain the upward motion of the helicopter.Teach Newtons three laws of motion 1)    An object at rest tends to stay at rest, and an object in motion tends to stay in motion with the same direction and speed. Motion (or lack of motion) cannot change without an unbalanced force acting.2)    Exerting the same force on two objects of different mass results in different accelerations (or changes in motion). The acceleration on the smaller mass is greater.3)    For every action (or force) there is an equal and opposite reaction (or force). Forces are found in pairs. Principles of air and flight.
