A small scale ‘wall of death’ experiment was set up to illustrate and to measure the forces involved. The experiment involved rotating a ball or a cylindrical tube inside a transparent tennis ball container so that the rotation frequency could be measured from video film. Static friction prevents the object falling even though the object rotates around a vertical wall.

死亡之墙实验
建立了一个小规模的“死亡墙”实验,以说明和测量所涉及的力量。实验涉及在透明网球容器内旋转球或圆柱管,以便可以从视频胶片中测量旋转频率。即使物体绕垂直壁旋转,静摩擦也可以防止物体掉落。
