踊るクリップ (Dancing Clip)

Hello all, this is not a fake. Notice the clips rise whenever the train accelerates or de-accelerates, or, when the electromagnetic field varies itself: when it happens, the electrons in the clip are set in motion toward one of its end creating a repelling force strong enough to rise up the clip's end. OTH, whenever the train is in motion, but in Uniform Movement there IS electromagnetic field indeed, but it is constant - so no electrons are set in motion, no repelling force is created ;-)
