Exploding Balloons, Deformed Balls, Strange Reflections and Breaking Rods: Slow Motion Analysis of Selected Hands-On Experiments
Vollmer, Michael; Mollmann, Klaus-Peter
Physics Education, v46 n4 p472-485 Jul 2011
A selection of hands-on experiments from different fields of physics, which happen too fast for the eye or video cameras to properly observe and analyse the phenomena, is presented. They are recorded and analysed using modern high speed cameras. Two types of cameras were used: the first were rather inexpensive consumer products such as Casio Exilim cameras operating at frame rates of up to 1200 Hz for reduced image sizes and the second were higher quality research cameras, which allow much higher frame rates at larger image sizes. In this first article, examples are presented from exploding balloons demonstrating retardation in mechanics, karate hits, deformations associated with the bouncing of balls, strange trajectories of "superballs" as well as the breaking of spaghetti. (Contains 19 figures.)
