The killer feature of mowers turns out to be the air flow generated by the machine which makes it possible to cut the grass even. The clip goes into detail on how it works and in an excellent series of clips, shows how it looks like at 50,000fps using a Phantom Camera.

We have to share some amazingly cool slow motion videos we came across recently. There is continuous production of quality high speed content as the democratization of slow motion cameras is happening. However there is so much content being produced that is sometimes easy to miss.
The videos below are using Phantom cameras or experimental cameras in the mid 20th century capable of 15 million frames/sec to capture the initial fireball of a nuclear detonation. That rapatronic camera used an array of separate camera modules to reach that speed. However the frames recorded only were fractions of a second
