Two metronomes are placed on a common base. The metronome on the left is set at 192 beats per minute. The one on the right is set at a slightly lower rate. The metronome pendulums are initially out-of-phase. The two pendulums oscilate in phase due to conservation of momentum and coupling via the base. A true physics masterpiece!

Synchronisation of 5 coupled metronomes done in Lancaster University, Physics Dep, Nonlinear dynamics and medical physics group. Emails related to this video can be sent to: a.bahraminasabNOSPAM at gmail dot com. Some explanation by ’shoonya’ which I think is pretty good: Here you go: metronomes (or “pendula”) when on table, oscillate with random phases, since that is how they started and they are “uncoupled” (no energy/information flows from one to other so they do not “know” each other.) When they are all together on the cans, notice that the cans themselves oscillate little, providing coupling/information crossover. which forces “synchronization” in periodic systems (discovered by Huygens in 17th century). A useful book: “Synchronization: A Universal Concept in Nonlinear Sciences ” by Arkady Pikovsky, Michael Rosenblum and Jurgen Kurths.

nice beat
Looks like 2 robots wiping the floor ,lol
WHOAAAA
WOooooooW i’ve watched all the video !! hypnotk 5/5 stars
what’s that? a crazy tempo game? #LOL
i hate when windsheild wipers do that.
Is this what geeks do to kill their time?
THEY ARE GOING TO TAKE OVER THE WORLD
where did you get those funky little metronomes?
@Dooohicky its called metronome it is to help psychics clear there mind and enter the alpha state of the paranormal word try relaxing with only 7 mind functions working and it may happen
0:53 dont you just love up beats
this video is better in my opinion watch?v=QkXHwRf15Ts
they clearly are not in time with each other or is something else supposed to be happening here?
wtf….they’re like, intelligent beings or something. freaky
thumbs upp
thats pretty sick
Wow! cool
Wow!!
Wait… It was fun for a while, and then… They Stay In Phase?!!! Whoaaaa.
Excellent video, I am surprised that the interaction between metronomes is so fast.
I have managed to synchronise 3 pendulums electrically of 3 Bürk master clocks, via a 30 second impulse from a Gents master clock.
Wow, I just came in my pants!
were any animals injured during this..?
it’s the coke. Unsicronized liquids.
Husband and wife inside the house and outside.
bizarre
Try that with a digital metronome – I dare you!
im scared
She’s rancid anyway but then again a boob’s a boob s’pose – - Naked Lady Gaga. C0000M -
@bobdahaxor Same happened here… /watch?v=gQK21572oSU
Hey mr. Abahraminasab check it out… and see if you find the corelation. I think you gonna like this !
/watch?v=gQK21572oSU
word….witchcraft
Yeah, cobber, a couple of cans and we all play in time… cheers!
@bobdahaxor This is sarcasm.
OMG I see the face of Jesus in his shirt! Get your shirt up on ebay quick….haha fifty thousand million billion dollahs…haha. I use a metro for fight night 3!
We should make energy out this
@grogsitreserve LMAO!!!!!!!!
whooooa! thats coolio
O.O ohh
i see… the weight of the ticker hands are fixed, all are the same (hopefully if there was no manufacturing error). without the cans, the tickers are not relative to each other, due to the fact the tickers are acting independently compared to the others. but when the cans are added, the weight is distributed randomly and the balance of the plank is rapid. the weight of the tickers move side to side simultaneously because of the tickers closest to the cans, shifting weight side to side.
Sympathetic Harmonics
fantastico
Altogether now!
that’s a pretty amazing phenomenon.
Entrainment is the process whereby two interacting oscillating systems, which have different periods when they function independently, assume the same period. The two oscillators may fall into synchrony, but other phase relationships are also possible.
Now what dose this mean for brain waves and Heart beats?
Science you just Mind-eff’d me again.
its dumb. A first grader could have done this. The cans let it roll which moves the board take the momentum through the pendelums. easy
Wow that’s incredibly cool! It’s truly mind-boogling to try and understand how it works haha
Thx for sharing!
the rolling of the cans must use the momentum of some of the pendalums to synch the other ones
stumbled from the next room over. someone left some shit on the floor
how is that possible? it seems like that would require changing their paces.
