No, you see here in this one they're using kilometers. Now if these scientists had used miles per hour as god intended, you would be seeing more of that juicy wiggle and splat we've all grown to love.
At one point in time--perhaps this is still true?--golf balls had rubber band innards wrapped around a very small plastic do-dad. I know at some point some balls were all plastic do-dad beneath the waffled outer shell.
Maybe this is one of the all plastic, while the other video is a rubber band based ball?
