Air lifting toy using the waste compact disk plate

摘要

The present invention relates to an air flotation operation playground using a compact disc to be discarded.;Although elementary and middle school students learn about air pressure and buoyancy, it is difficult to actually experience the change caused by the difference between air pressure and buoyancy.;The present invention was made on the basis of the compact discs that are discarded a lot of existing plastic bags and small motors to produce the play principle of operation principle, such as an amphibious hovercraft by the wind generated when the motor rotates.;Therefore, elementary and junior high school students make air-floating playground equipment by using compact compact discs, plastic bags, and discarded computer's CPU cooling fan. They sought back together to experience these physical changes directly.
