It can also appear to levitate for a period of time after it has been dropped, and make spooky sound effects! As well as being a classic toy, the design has appeared in the classroom as a teaching tool, in wartime as a radio antenna, and has even been used by NASA in zero-gravity physics experiments. It can be used to show the principles of Hooke's law, to simulate the properties of waves and demonstrate the effects of gravity.Popular Science publication has been a leading source of science and technology since its inception in 1872.
