The disc of a partially dismantled computer hard disc drive being illuminated with a high speed stroboscope. As the flash frequency of the stroboscope is lowered to 7,200fpm the white mark on the disc appears stationary. This is due to the mark being illuminated once each rotation and hence the rotational speed of the disc. 

Initially the mixer paddles are seen to be in motion and the water vigorously agitated. The jug of water is then illuminated by a stroboscope set at 1,300fpm at which time the paddles appear to stop moving though the surrounding water appears to boil. This is due to the mixer paddles being illuminated once each rotation and their motion apparently frozen whilst the water is in chaotic motion.
