Concept 2: As you push down on the pump, there is a blast of air that pushes the soldier up. As the soldier flies through the air, the parachute opens up and lands safely on the ground. The principle that guides this design is air pressure. When the pump is pushed, air pressure will push the soldier up into the air. The launcher will be made out of plastic as well as the soldier. The parachute will be a plastic attached to the soldier by string. Durability is a key aspect of this design. The pump must be made to last.
