That looks like a chain made specifically to do that.
Adam Savage is going to be all over this!

So is the snap at the end really the whip hitting mach speed? I could look it up but I would rather hear what all y’all have to say.

This is a pretty comprehensive explanation…

I don’t want science! I want people arguing like they used to in bars!

Arguing in bars with whips?

Man. I went to the wrong bars! Best I ever saw was pool sticks!

Sticks and stones may break my bones,
But whips and chains act in accordance to the laws of physics.

Wtf, i did not expect that. Chain appeared to be moving slowly and thought the whole thing was an amusing joke. And then the chain actually cracked and i was shocked 0:

great video, thank you! (man, and april choi is just so awesome in every possible way!)

It appears that each link in this chain is slightly smaller than the last, so that the effort that the whipper puts in at the large end is magnified as the wave moves down the chain to the fine tip. Each link being lighter means that less energy is required to move it, so that more of the energy can move down to the next link of the chain.
This is a non-researched guess, so if I got the science wrong, feel free to rip me a new one (theoretically speaking).

My girlfriend and I once stayed in the Puszta in Hungary. The place had a hotel and a bar and nothing else. The hotel wasn’t serving food, so we went to the bar for a dinner of peanuts and beer. We sat at the nice big table just outside the door. Then the local arrived. We had apparently sat at the wrong table. Nobody complained, but we were given a ‘special’ demonstration of their skills with a bullwhip. We sat, trying to hold a normal conversation, with the tip of a 5 or 6m whip flying past close enough we could feel the ‘breeze’. It was an odd evening. (But/And a fantastic country - I recommend it!).

Except for the creeping fascism of course.
I was supposed to be in Hungary for a conference right now. It’s all online now but that’s no substitute.
Yeah, good point. It’s getting harder to avoid creeping fascism these days. How sad 
(Online conferences suck, but I think they’re here to stay. Can we really justify jetting around the world for a one-week jolly while the world melts and burns around us?)

Yeah, and the actual presentations are working a lot better than I had expected. But it’s the networking (or as we used to call it: getting to know people) that’s almost more important and that part is pretty much dead. So I don’t think they’re quite there yet as an alternative to the real thing.
It’s especially frustrating because this is the first time I’ve actually had a budget to go to conferences like that, rather than having to scrounge up the money myself. Just as I have gained that freedom it has been taken away again.
