The shorter the cycloid, the smaller the allowable error and the greater the difficulty of installation.So our pendulum manufacturing requires a lot of time</li><li>The swing will present several shapes of waves, which are very beautiful</li></ul><br><br>Pendulum Wave Physical Science Desktop Decoration:12 Balls,Not Newton's Cradle,Huygens Pendulum Principle
