This video purports to show a golf ball striking a steel plate at 150 mph, with the action filmed at 70,000 frames per second. At several YouTube postings of the same sequence, the discussion threads are dominated by incredulity, with opinions being presented that a real golf ball cannot deform to this degree, and that what is shown is another type of ball resembling a golf ball, or else pure computer graphics (or, as the YouTube crowd says, "photoshopping.") The discussion at Neatorama will presumably be more intelligent and well-informed. What do you think? A real regulation golf ball?
