Pick up a steel ball by sticking it to a freshly washed finger and drop it into the capillary tube. This works better than using forceps. When dropped into the capillary, the tiny ball is usually stuck at the air-liquid interface. Use a magnet to move the steel ball below the meniscus and to a desired position inside the test solution.0.33 mm height (Figure 2). Steel balls with diameters of 0.50 inch (1.27 cm, 8.35 g) and 0.75 inch (1.91 cm, 28.20 g) were used. For every steel ball, a different steel ball guide was used to ensure a proper drop [26]. Any visual observation of decomposition was consid-ered a positive result. After each trial, the remaining materi-In the test, a metal ball of 500g with a diameter of 50mm has been dropepd from a height of approx. 130cm and hit the monitor without leaving any visible damage or even splitting the glass of the touch screen.
