That was awesome
Ngl, watched the entire thing. BRILLIANT
That was a masterpiece, take my up
Why is this so mesmerizing
Ok, that was legit in so many ways. Def shared it.
I… Can’t… Stop… Watching.
I can’t believe how the person managed to actually mimic the vibe of the dance moves in the original music video.
r/oddlysatisfying
Pleasantly surprised
Well crap. Reddit is melting my brain cuz I actually enjoyed that.
This is a beautiful masterpiece! I watched all the way through and was completely mesmerized.
Hypnotizing. Even though I understand (very basically) how Newton’s Pendulums work, it still amazes me that they work.
This is more interesting than all the shitpost in r/damnthatsinteresting lately.
This is way more entertaining than it has the right to be
You made it too easy to imagine Psy as one of those bearings
I’ll be damned if this isn’t shown in every high school physics class in America
This is the first time in my life I’ve listened to the whole song and it’s all because of physics
Omg all those sonic booms!
Heyyyy sexy cradles
I love how well this works and looks like a “simplified” version of the moves from the music video. Absolutely mesmerizing.
Also had no idea there was so much variety in the patterns you could create with the cradle.
And that internet, is how the pendulum sales gained +12% on their sales worldwide on a single day.
PSY-IENCE!
I was both laughing throughout the whole thing and mystified by how well done this is
I was not aware there were so many different patterns that could be effected. I guess I’ve never had one to idly play with other than at museums.
First few seconds: “This is the dumbest shit I ever saw”
Halfway through, grinning uncontrollably: “… A’ight, so maybe I was wrong”
Wanna feel old? Gangnam Style came out 10 years ago.
I was trying to see if this was manipulated to be faster or slower, or if he has a Newton’s cradle that syncs up with Gangnam Style, so I did a little math. Gangnam Style has a tempo of 132 BPM, which is 2.2 Hz, or a period of 0.45 seconds. A pendulum’s period is 2*pi*sqrt(L/g). Solving for L comes out to about 5 cm, which seems like a feasible length for the pendulum of this Newton’s cradle. I don’t know the specifics about this Newton’s cradle or anything, just that it’s feasible he could have one that syncs up well.
Edit: I’m probably wrong. I think there’s 2 impacts per period, so an effective length of 20.5 cm. This is if the pendulum had a single wire, which in a newtons cradle it doesn’t. So the actual strings are probably a little longer. If I’m right this time, this would have to be a pretty big Newton’s cradle.
Can you imagine how many views this would’ve gotten in 2012?
This has to have been the most entertaining shit I’ve ever taken
*Newtons Cradle
5 seconds in: hah, yeah, I get it. Not like it’s worth watching it all though.
2 minutes later: damn it.
I watched with this wearing earphone and snort out some laugh in the train, and guy beside me give me the weirdest look almost saying how the f is these swinging pendulum is that funny…
