A pistol bullet with a top speed of more than 50 miles (about 80 kilometers) and an acceleration of more than 0.22 inch (5.588 mm) can produce an impact force of up to 60 kilograms. The high temperature caused by friction can even make the surrounding water spark. Once, a scientist was caught in the sea wearing gloves, his finger was injured and he was bleeding profusely.
