Tim Rattles his Rattlebacks

A rattleback (also known as a celt or a wobblestone) is a type of spinning top that will spin in one direction, but when you spin it the other way it will slow down until it stops, wobbling along its length, and will then spin in the opposite direction.
Originally seen as mysterious, they are now regarded as an interesting piece of physics. One of the original papers explaining how they work was presented at the Royal Society in London in 1988.

The little turtles who don't want to go backwards are just lovely.

[@jfnuyen]

Tim, that is one item I have never seen in my life, but apparently it is rather common. Very cool though.

[@drpriest04]

Toy makers are simply amazing, a scientist , an artist.

[@angrysmerf]

How anyone can actually dislike these videos is beyond me.

[@HetThakkar809]

Sir Stefan Channel! *can anyone

[@SOBIESKI_freedom]

Het Thakkar Sir Stefan's grammar is correct.

[@SOBIESKI_freedom]

Het Thakkar The subject of the sentence is a noun clause, which means the subject in the noun clause is followed by a possible auxiliary and the main verb. This noun clause itself acts as the subject of the sentence, which is itself a positive and assertive sentence - not a (non-assertive) question. A (yes-no) question inverts the the subject and auxiliary. I hope that clarifies it for you. Best regards, Your grammar and syntax Nazi.

[@HetThakkar809]

Thanks for clearing that up.

[@SOBIESKI_freedom]

Het Thakkar You're very welcome. (We grow and learn. ;))

[@ThatBaueRGuy]

Oh my god, my grandparents use to have one of these, i never understood why they had that weird piece of wood till now!

[@telochgah7806]

I'm glad there so many people watching this, Tim is just so charming almost like Bob Ross, which I've also started watching again because of these videos

[@Postboy]

The phone at my work does this. I find myself spinning it all day.

[@PhoneyMacaroni]

Press 1, 2, 5 and 9 on your keyboard to hear Tim say "Rattleback"

[@thefluffinator229]

***** Endless seconds of entertainment

[@eyescovered]

***** Fantastic.

[@MrTinytadpoletim]

***** 9, 5, 1, 2 provides the most auditorily pleasing combination, imho.

[@ChaosBW]

***** Rattleback unintentionally.

[@channelfadge7438]

Babby Babbyson on 1 he actually says 'rattleback one', extraordinary!

[@ogelnac99]

I don't care what everyone else says, this channel is most excellent.

The truth is out there my friend, rattling back somewhere....

[@guitarbrad]

Once again an excellent video! Tim is always so entertaining - he's great. You always seem to find such interesting things and he has such a cool collection. Keep up the excellent work!

[@BlueMelonTheBloodBun]

Love seeing these videos!

[@CFlow375]

Always amazing how Tim can make something so simple so interesting

[@Zolwena]

I so love watching your video's and rattlebacks are a favorite of mine! I have a few at home and I have made many and shared them! Awesome items!

[@mikek6298]

Ah, the first video of yours I'd ever seen. What a time it's been!

[@UnrealKeyboards]

hope to see tim at rattleback-con this year

[@jondabron5496]

When I first saw this I went around spinning everything and I found like 12 different pens that worked as rattlebacks

[@Forkoto]

i have no idea how i found this video, but i regret nothing! :D

[@tyguy6296]

what do you think happened to Vladimir krasnikov back in the 80s? did he really disappear? or did he get too close to the truth about UROs?

[@mistercaptain6102]

I didn't even know these were a thing, pretty neat

[@thefaceofawsomeness491]

It isn't a canoe, it's a gondola, which are actually made asymmetrically.

[@seanconfer7903]

Tim, my birthday is in 4 days and I love your videos. I also love all sciences. So maybe for a present you could make a video about any scientific gadgets/toys or the like that you may have in your collection? :D :D

[@MickeyD2012]

99 more tiny longships and you can stage a tiny Viking invasion.

[@EmmanuelEXEf06]

Nice last part of the video too ! Cool item :)

[@ampersandasmr1294]

Governor: Warden, the children of Switzerland demand rattlebacks and I'll be damned if they don't get them! Warden: But sir, don't you think having prisoners craft a metal toy that looks a lot like a shiv could be dangerous? Governor: No. And that is the story of the Great Swiss Jailbreak of 1968.

[@robertbrookes2000]

My Science teacher showed us a video of them and they looked awesome!!!

[@AV1461]

I had a cellphone that rathled back. Probably unbalanced by it's antenna. Used to play with it a lot when bored, but didn't really pay much attention to the rattlingback..

[@jeffcolorado]

Very interesting. I didn't know there were so many varieties of rattlebacks. I have one similar to the one that also magnifies. Another feature of that one: press down gently on either end, and the rattleback will start spinning without a "push".

[@billyd4eva]

Rattle's got back.

[@skakdosmer]

This makes me wonder, is there anything that Tim doesn't collect? Well, nobody's going to rattle my back! I only shake my head.

[@VMeGaMRedZV]

Tim himself probably can Rattleback using his body too or is there any Rattleback version of Tim out there? Just curious. Take it away boys. lol

[@emadabdelnour3803]

Thank you Dear Tim, I wish I could meet you one day , good bless you

[@OatmealDonk]

you sounded like one of my high school teachers at the end. :-P "wow!... there's movement!"

[@jagscircuitt]

Tim has friends from all over the world and they are too good.

[@pepupapi]

Prisoners made a shank and told everyone it's a rattleback.

[@josecortez2687]

Marvelous

VERY clever.

"All rainbow rainbow rainbow" XD

[@Not_british2.0]

So how do u explain how in the video "Selecting Rattelbacks,2000 years ago " here on KZbin where the guy picks up random rocks on the shoreline and they do the same thing?

[@thefluffinator229]

Tim can you do a documentary on unusual U.R.O.'s and your collection of exotic rattle-back sheets of paper

[@neweraccount5615]

So it’s all due to the design on the bottom? What about the smooth ones?

[@johnnyj540]

I didn't even know what a rattle back was until today.

Can I get one of those turtle rattlebacks somewhere?

Rattleback from the Nile

If you bend the iPhone 6 in a certain way, it turns into a rattle back.

This is why Ipads were invented.

Most of the toys are from Tim's collection, and are not for sale.

How many pokemon have you collected?

Rattlebacks... How do they work?

[@narwhalsheckyeah]

Now i have an ugre to spin everything in my house to see if it rattles.

Having an ugre can be painful, see a Doctor

[@christopherdocy5864]

the captions are a war drama

[@marsha414]

Huh I just watched this for physics class , neat

[@TensionBoogieWoogie]

I might just be missing the point, but what is the point?

[@Goddygoddy1]

Ayygent of Teal the way it rattlesback looks like its violating the law of the conservation of angular momentum.

[@TXiCN]

Ayygent of Teal Gentleman: "Now try to spin it clockwise, my sweet." Lady: "Oh! How magical!" And then they both laugh and the dude get some tail. Fact.

[@TensionBoogieWoogie]

More rounded than a point but A for effort

[@creadcharles]

Ayygent of Teal Playing with rattle backs is even more fun than watching a video of someone else playing with them. Buy one yourself if you don't believe me!

[@sock2828]

+Ayygent of Teal What's the point of a spinning top?

[@RenkoBernkastel]

2.000 Deutsche Mark for a rattleback? That's a month's worth of work in a rather good position

[@MrPleers]

***** Too much money for a simple piece of wood.

[@Lollercoaster119]

I guess it's that much cause he said it was large and made of mahogany which is a really nice wood

[@MrPleers]

Mahogany is nice. But not 2000 Deutsche mark nice. For that price it should be solid silver.

[@rich1051414]

***** Thats only about 1150 USD... Good position? Relative to what? I agree that is a lot for a chunk of ill balanced wood, but is that really high for a months pay in germany? That is roughly 1/3 of the average monthly income in america, in fact, that would likely qualify you for foodstamps and damn near what the US calls the poverty line(about 1000 USD a month) and would be heavy poverty in some states.(Up to nearly 2000 USD in some states without medicaid).

[@TruthNerds]

The Euro was introduced in 2001. Around that time, 2000DM was an adequate salary let's say for a shop clerk, full time, but not for anything I would call a "good position". Even as a qualified worker ("Facharbeiter"), e.g. for CNC turning, you would already gross about twice that, on a 35 hour work week.

[@zoraxbrooks]

Wow

[@peterawesomeness1]

I want one of those prison shank rattle backs.

WHY am I watching this at 1am???

Hi! Awesome video. Where did you get these rattlebacks? I am especially a fan of the light show one! Have you been collecting for years? Let me know. Amandine

[@TruthNerds]

Finally we can get rid of these tired old lightbulb changing jokes and replace them with "How many X does it take to spin a rattleback?"

[@Chimera-man-man]

Why don't you add some weights to a canoe or kayak and rattle that back and forth?

[@hentkovind9018]

Boyd Bushman had one of those. It spins in a certain direction because of the spin of Earth?

[@Mrniceguy21107]

Not even close

[@hentkovind9018]

MrNiceguy21107 Really? That's what he suggested, and he's an engineer... So.. Hmm, believe him or some random on YT?

+Hent Kovind thats not what he suggested, or even close to it. Check the video again, hmm.

[@hentkovind9018]

MrNiceguy21107 Ahh ok so David Sereda mentions the spin of Earth, & Boyd pretty much says 'idk'.

[@markdoldon8852]

No, essentially that will happen to any similarly shaped object that isn't perfectly symmetrical.
