Thank you! You've solved two mysteries for me as I once had a video game explode in a CD drive and I've heard that rolling noise before without having any clue about why balls would come loose.

Hi Nick, I was running thru my subscriptions in the youtube interface (view all) and when I saw your icon I was so excited and burst out load with a "yes"! With YT's additions of "shorts" to the youtube interface the algorithm for me has "lost" all of the great things that I loved about youtube, like content creators such as you! I immediately watched your latest video and was so rewarded by your awesome content. Super interesting! I remember as a kid "hacking" the safety switch with a pencil to watch the top holding cloths washer go thru it's cycles. I watched in wonderment how the spinning drum could have "self righted" itself when the clothes were initially out of balance. I was imagining a type of counterbalance system that would take the "cam" input (movement) of the drum and and via pushrods try to add a counter weight to self balance the spinning drum. I guess is I was maybe 10 years old in the 70's when I made this observation. But it was not until today that I learned there is a much simpler way to handle this problem. It was probably a good thing I did not try to take apart my families washing machine to find out. But I did want to thank you for sharing the solution these 54 years later! My mom thanks you too! (from the other side of that rainbow) Again I need to realize that I cannot rely on the YT's algorithm. Thank you for continuing to add content and I will do a better job of seeking out your channel. You are the best! your friend out in the ether, alan

What happens with the almost balanced bottle without the bolts? That's a more realistic example, right? Because discs are somewhat balanced, not perfect, but not crazy like with the bolts. Do the bbs spread evenly, or does it add IMbalance?

Wow, I need to throw some ball bearings into my old washing machine

Mighty interesting, thanks for the Video !!

Interesting effect, nice video explanation as usual!

I feel it somewhat related with Hula-hoop with a bit of sand inside.

Extremely ingenious. I never heard of this system before. Also @ 4:04 Meow!

Washing machines use this method to prevent shaking during the spin cycle. They have a balance ring partially filled with fluid (lightweight oil I believe). If the load is unbalanced, the fluid redistributes in the ring (much like the BBs in your demo) to counterbalance the load.

I think that System was made for the advertisment CDs back then, they came Laser cut to different forms as Gifts sometimes. They weren't round at all and I always wondered how come they didn't explode in my 48x drive

The most common mobile phone keyboard type in Japan is almost the same concept as the Message Ease keyboard. This is because Japanese has almost 50 phonetic characters.

That's a great demo! I always wondered how effective this approach really is.

Hiya Nick! I have seen the tire balancer beads before; there are videos on KZbin where someone mounts a gopro to the inside of a rim, and put the wheel on a tire balancer. It did seem to show the tire balanced. However, when driving, there's going to be a lot of deformation, and I doubt balance will be maintained; probably worsened. I think the ABS-like systems are more for steady-state operations, such as clothes in a washer during spin cycle (I believe water is used to balance laundry loads), or the weight of ink on the label of a CD/DVD/Blu-Ray. As for what to do with 900 BBs... still have that cannon? :) See ya!

If anyone can think of any projects that involve ~900 BBs let me know. I only had about 100, of the 1000 that I bought, fly off into the garage.

Physics is so interesting! This is one of those things that, at first, appears totally counterintuitive, until you think about it for a long while and suddenly get it. Man, the people who came up with this in the first place must've been geniuses! Thanks for the vid. Really appreciate your vids. :)

Really cool demo of the idea!

That was a great demo! I find the physics of this hard to understand, but its hard to argue with your demo. The balancing balls placed in your car tire do actually balance the tire. KZbinr Warped Perception put a GoPro camera in his car tire to demonstrate the balls moving to a spot to balance the wheel...see kzbin.info/www/bejne/i4u0iYOCm7SDjsU for his video.

I've been using the beads inside the tires of my work truck for years now. Brilliant invention. I deal with a lot of very bad mud that can build up inside the rim and I was always loosing wheel weights when I would pressure wash the mud out. They're not as good as wheel weights when compared to good wheel weight application but for me they are a life saver.

Neat! I wonder if you could make a self-balancing spinning top like that?

First I have seen such a thing and explained well too. Good to see you back.

I always thought those tire balancing beads were a scam product. Incredible to see how they might actually work!

How does it know overtaking? Or 16 wheeler trucks?

Micro Mages, lovely!

Clear epoxy might do the trick with the dings. Nice paint job!

It's been awhile! Welcome back!

I literally just got a CRT to use my new-to-me refurbished NES collection. I might paint mine like this, cool idea.

Look's cool Nick!

"Found on the side of the road in a ditch" I mean, there are worse things to find after last call on a wednesday night...

Bombus impatiens.

power factor?

Worked for me! Had the oily and slow aperture, now it's perfect. Thanks

Best explanation out of all the videos I've watched so far...was getting worried that i wasn't able to grasp onto the concept. Thank you!

0:27 triple point

Okay now that's dope

geometry dash reference

How is this different than a flex sensor?

Did you catch Paul?

That's not just a normal spring it's tortional spring

Great video!

I made a jig for spooling 35mm film onto the backing paper from medium format rolls so that I can load it onto 127, 620 and 120 spools. This way I don't have to modify my cameras at all. I've considered making the plans available for anyone that wants to make their own. But it'd involve access to a laser cutter.

Thank you!

The thing is that magnetic lines become horizontal at a very short distance from a cylinder magnet pole. So, your foil moves left-right more than back and forth. Then rotate it 90 deg clockwise, and it will be louder (and displace it from a center of the magnet)

This is genius thank you

Everyone talks about winter being such a depressing season, but this timelapse is a great illustration of one of the reasons why I love winter. In winter, when the trees are bare, you can see more of the outside world around you, it's like being in a room with the blinds open. Where I live, there's a small patch of woods across the road, but in the winter, when the trees are bare, I can see the lights from downtown in the distance from my bedroom window at night; in the summer however, when the trees are full, I can't see anything, and it feels like being cut off from civilization.

EXACT issue I was having. THANK YOU!

There is some useful fluid dynamics information there. Very interesting how the arc follows a jagged path in the already ionized air until a substantially shorter one is found.

How i can made effect like hp

Great demo! I've been experimenting with both pulling vacuum and just boiling off water in diy heatpipes to set them up but not sure what is simplest. I've also fiddled with a better demo where center section is glass. It is hard to get a transparent wicking material though as I want to show the transfer of liquid back to hot end also when horisontal.

SO COOOOL LASER DUDE,,,,,PUT A LASER ON THEM ./////TAKE OLD PROJECTORS APART..... COOL....

My source is an Allanson transformer (oil burner) that can be connected to the variac. Does the current matter? My source produces max 23mA at 10kv. Is it enough current?at round trap i have 2 equal 16mm hemispheres, what is the diametter of the ring 16mm or 20mm is good, or less?please reply
