I really enjoy watching The Slow Mo Guys on YouTube, but this video actually scratches a different itch for me. The Guys are almost clinical in their videos, whereas this takes a more artistic approach. Love it; well done.
One of my favorite high speed camera youtube channels is Love High Speed, which shows videos filmed with much faster cameras.
Here are some examples:
Water Balloons explode at 5,000 fps - 
A liquor bottle explodes at 12,500 fps - 
Super Slow Motion Droplet Collisions at 12,500fps - 
Some of the cameras they use - , ,

It only took a mind-boggling 800,000 FPS!
There's something fascinating about how the brain can instantly switch on to full attention when intrigued. The way that the videos are composed completely dismantles the reality as nothing acts as the way you expect it should act, you can even feel in your body as your brain tries to adjust in this new reality. It's like seen a slo-mo for the first time, again.
The video that I was presented is the one at 0:53 on this one. The continuous motion of his hand with the clock captures your sense of progress over time as it is the only thing that works as expected. That itself is cool but as he moves his hand beyond the point of re-assembly of the broken bottle, the bottle breaks in a different way and this conflicts with your intuition on the way the world works even if you are slo-mo junkie that is used to see things decomposing in million pieces and re-composing to full shape...
As his hand passes the point zero, it feels like the bottle breaks again because he moved the time too much and this leads to feel the time as a rigid physical object due to the way the bottle breaks.
I remember going through backwards videos in thermodynamics class, because the interesting thing about reality is that it has charge, parity, and time reversal symmetry.
“ The implication of CPT symmetry is that a "mirror-image" of our universe — with all objects having their positions reflected through an arbitrary point (corresponding to a parity inversion), all momenta reversed (corresponding to a time inversion) and with all matter replaced by antimatter (corresponding to a charge inversion) — would evolve under exactly our physical laws. The CPT transformation turns our universe into its "mirror image" and vice versa. CPT symmetry is recognized to be a fundamental property of physical laws.”
This is pretty recent.
I don't think so. CP violation means if you flip charge and parity, you can tell the difference (the Kaon experiment).
But if you flip charge, parity and time all at the same time, so far there's no experiment that says you can tell the difference (CPT symmetry).
In fact, it is my understanding that CPT invariance + broken time symmetry implies broken CP symmetry.
For five grand however you get a lot of potential to get good research done in a budget, heck you could even buy a few of them and mount them on something moving since they are battery powered.
I bought the similar FPS1000 camera a few years ago and it had a lot of issues. It was really buggy and poorly built. The Kronos looks a lot better.
I always enjoy these kinds of slowmo shots, similar to the Quicksilver scenes in the X-men series.
