we start with mechanical energy where some one pushes the button to move the ball. The ball will drop and go on a seesaw. The see-saw will go up and will hit a switch to turn a hair dryer on high. The switch will turn a pinwheel really fast and it will push a race car.

The poppers used elastic potential energy. The elastic hit the surface ,making the popper create kinetic energy. The popper will go up and reach its max potential energy and convert back into kinetic. The popper will hit the ground again and will become potential energy again. The kind of surface also had an impact on the height of the launge because if the surface is soft, it absorbs the impact of the popper popping but hard surfaces absorb none.
