Each of us has our own understanding of the laws of physics. These beliefs are formed through personal experience (falling out of a tree), classroom education (an apple falls out of a tree) and much more. My own experience has taught me that the way we experience physics everyday is not the whole story, it is simply the way things are under “normal conditions”: change these conditions and everything can change. In relation to this, most people would say that golf balls are solid objects. However, as shown in this brief clip, fire one hard enough at another solid object, and it starts to display some very liquid properties. In real-time this deformation would be too quick to see, giving a truly educational example of the gulf that exists between our perception and reality.

Interestingly, as an avid golfer I have seen photos of golf balls deforming on impact, but the extent of the deformation shown here really took me by surprise. I would guess that the speed of impact is significantly higher than the 160km/h that good golfers can achieve
