I suspect his kids would be more inclined to participate in every science fair they could enter whether they win or not.

Step 1. This man shows something that seems impossible, or just crazy.
Step 2. My mind is broken.
Step 3. He proceeds to explain the science behind it.
Step 4. I fully understand how it works.
Step 5. My mind is still broken.
Step 6. I start watching another one of his videos.
After reaching some speed, the inner ball would be stuck to the outer one because of the centrifugal force. That transition could be interesting.
The ball wouldn't reach that speed since the friction between the metal ball and the molasses is proportional to the speed, so the friction and the horizontal component of gravity would at some point cancel each other, therefore the ball not accelerating anymore but travelling at a constant max speed.
@@Pietro_Troschka From what you're saying, I suppose that means in order for the ball to move any faster, it'd need to overcome the outer friction, so at that point it's just sliding.
I doubt that the ball could reach that rotation speed by just friction and gravity. If it reaches it by some means, that ball would spin around the center of mass so i guess it would look "wonky", spinning one side of the ball faster than the other.
@@Pietro_Troschka Theoretically the friction would cause enough heat to lower the viscosity of the molasses, allowing it to roll faster
Especially if the molasses just sticks to the surface
This was a spectacular use of COG manipulation. Good one James

Another mass-distribution experiment you could try is to make four of these hollow balls and roll them around - one with a dense mass suspended in the center, one with two dense masses at opposing poles, one with a dense ring around the "equator", and one with a dense shell just beneath the surface.

I would love to see a race between jars filled to different amounts.
The closer you get to exactly half way the slower, bit once you cross half way it is the opposite, it will get faster.
The only reason you would want it Slightly above halfway is to compensate for the amount that coats and clings to the top half (empty space), But you can't beat flawlessly half way!
I’d also love a racewar
Also different liquids.

Some sort of viscous liquid was my first suspicion! Kinda surprised you didn't mention that the slow ball's speed would be temperature dependent when molasses was used.
Because moles are warm blooded? Who is manufacturing this liquid mole ass? I wouldn't want to live next to that factory. I bet it stinks.
Would it not roll at all if frozen or near frozen?
@@morphingninja Molasses flows even at very low temperatures, but slowly.
Even in a deep freeze at -20°F it will flow. I suspect honey would work as well.
More interestingly, the more you'd roll this ball the less viscous the molasses would become (as it would become warmer) so it'd get faster...
Had this been filmed in USA global warming would have turned the molasses into vapor

Imagine doing this same setup with everything transparent.. Like the outer ball is transparent, the fluid inside is transparent.. 🤩
That's Steve Mould's channel.
Your work is amazing, thank you so much!! I know that maybe things are not the greatest, but I really really wish this channel all the success and longevity
When I first saw the ball rolling so slowly I initially thought you had filled it with honey, but I guess molasses is a bit similar. I still like your videos though and hope you keep making more. 👍
Ah, the classic honey-filled ball from the old CZcams videos, OGs should know 😎
@@red_dulge guess I'm an OG then
I thought he had one of those sticky balls from vending machines that crawl down walls in it.
I am a mechanic, so I thought high viscosity oil, and then non newtonian fluid.
Slime is what poped into my head first. Done this with my kids and slime jars.
I didn't expect the metal ball tho.
before you showed us that it was molasses inside I thought it was a thick liquid in side there BUT there were fins sticking up into the liquid (on the inside)..... I wonder if that would affect its speed anymore than without them?
very cool :)
Shouldn't affect it too much. For that to work the liquid inside of the ball would have to remain stationary relative to the ball. Which it doesn't, it would be spinning at pretty much the same speed the ball is spinning.
Curved fins, like a water turbine. Extra super 🐌 slow I bet
@@HouseExpertify right... because the liquid wouldn't drip back up the fins ...I follow
@@HouseExpertify the fins would have to somehow stay oriented properly for anything to be calculated I think.
For that to work, the liquid would have to be incredibly dense. Could totally work with Mercury.
I'm going to make one for my niece to hopefully encourage her to ask questions and be curious about why things are the way they are. Great job with this! Excited for this project :)
That's a good way to bring up children. Show them some interesting phenomena in practice and let them ask questions and discover them.
how did u get the ball in half. which ball did u use
When I saw the wobble I was like “ah, I recognize that. You have a thick liquid or oobleck inside it”. I didn’t know about the heavy ball or needing a low center of gravity.
I am compelled to tell you that I think you are a wonderful being and an exemplary human!
I have watched so many of your videos now and
truly appreciate your perspective and intelligence, and kind curiosity
And most especially that you share such amazing, practical science with so many in such clearly considerate and joyful way!
I wish you much fortune, knowledge, and happiness!
Ameen!
Elegantly said!
Could you make an even slower ball by placing your slow ball in molasses in another larger ball?
its SnailBall-Ception
One could keep the current shell and heavy inner ball but use a thicker molasses blend or another viscous liquid. Hersheys chocolate syrup and Heinz ketchup are rated as more viscous than blackstrap molasses.
Temperature will also effect this.
@@MrBishop077 The viscosity of molasses increases inversely with temperature. Ever heard the old expression, "Slow as molasses in January"? Just put the ball in the freezer for an hour, that'll slow it down for a while.
The slowness of the ball probably increases with the amount of mass and it’s CoG distance to the ground. I’d say yes just have to proportion fluids and CoG properly.
@@LeffHynebridge But the force spinning the ball would increase also(meaning the g-force pulling the ball down the slope). Ratio of molasses resistance to the spinning force from the outside would be different. Ball would spin faster. Unless you replaced molasses with more viscous fluid.
Kalle- Thank You for all you do. From this year to the next please keep doing it, you are truly one of a kind!
My initial thought was a small heavy ball inside the larger ball, with a thick gel/kids slime inside creating the resistance of the small ball to roll, so I wasn't far off.
Brilliant explanation as always - love your videos as they are very relatable and get people to think about what's around us and what's possible. Keep up the great work - Love from Ireland🇮🇪 T😊
Since he said »So I'm in my house playing with ny ball« in an other video, I can't keep myself from laughing whenever he talks about balls
2:40 This reminds me of the roller on a road roller compactor. Lol
This takes as slow as molasses to a whole new level
I was thinking “the ball is sticky” and turns out it was, but instead of being sticky on the outside, it’s sticky on the inside.
This is an interesting idea that I think could be useful in creating a spherical wheel. Imagine what it would be like if the internal ball was what you were using to provide the torque. I think that you would want something much more viscous than what you were using. Maybe you could use asphalt or something else that would still technically allow movement but it would also allow the application of large amounts of torque while givong resistance in directions you don't want.
I legit was not expecting the ingredients used to make this. 😁
Cool video! I like that you got to point of the video and didn't stretch it out to the min mark by rambling. Loved watching your video for a few years now.
That ball just didn't get it's morning coffee

Crazy times for stupid things
I recognized the slow stuttery roll with a half empty water bottle :P. So I instantly thought there was a sort of moving mass inside. I didn't think of using molasses to make the effect more pronounced. Interesting video nonetheless.
This experiment really took some balls to perform.
TAL: "I have 2 balls of equal weight and volume"
Me: "Me too!"
I love your videos! I have a question about ice cube trays. When I stack one on top of the other, the ice in the top tray comes out a lot easier than the bottom tray. Is there a science explanation for this? I am doing my own experiment with this. I am not stacking them this time. I wonder if they will both be easy.
How many of you has skipped the sponsorship part
That is partially where the expression "slower than molasses in January" comes from.
I figured it out before you showed the cutout ! I feel so clever.
I was going to say molasses by it self would work. Gear oil might be cheaper.
..but wouldn't taste as good in coffee after
“I have here two balls of equal weight and volume.”
It seems the fast ball was much lighter. If not, what was in it?
Yeah, I'm thinking the same thing.
Weight shouldn't affect it anyway.
It doesn't really matter, second experiment show the full Molasses jar which is heavier rolling faster than the half fill jar.
@@neirad537 it does matter, if what he stated wasn’t true…
Dude just defies physics every video
What happens when you combine both mechanics? A half-filled sphere with a heavy iron core.
I Imagine you could also attach metal screens or steel wool or something to the inside of the Ball/Jar to drastically increase the friction with the walls and make it roll even slower
I wonder what would happen if you fill it with some newtonian fluid instead, would that mean the faster you try to roll the ball the slower it will try to go? Or the effects of a self rolling ball are probably just to low?
That would be interesting!
THE OOBLEK ACCELERATION DAMPER
"You just need to get the ball rolling and put your life on the right track"
The ball in question:
that ball is just takin his time
Cool. Are there any engineering applications that use this principle?
Reverse Soapbox races, where the last one wins maybe?
A deadblow hammer uses a similar principal. It uses a displacement of internal substrate to dissipate energy. Not quite the same principal, but similar. I actually thought this was partially filled with lead shot at first for this reason.
I believe most automatic transmission cars use clutches that use the viscosity of oil to generate the resistance between the engine and the drive shaft. The oil flow can be constricted and opend to vary how much resistance there should be. This greatly decreases wear, compared to regular friction based clutches. Its not entirely the same, they both use the viscosity of a fluid to create resistance.
Maybe as a dampener for keeping doors or windows from slamming shut?
@@engineer0239known as "Viscous Couplings" (similar to torque convertors used in A/T) but they use a fluid that thickens when electricity is applied.. or 'engage' as friction heat congeals the fluid,, very cool physics cuz most fluids lose viscosity when heated..
I wonder if the same setup would work with silly putty instead of molasses. If it does work, would probably only roll less than an inch per day.
He's one man bun away from making real scientists gag
“So I have two balls of equal weight and volume.”
Boys, it’s laughing time.
Great video, once again! However, I would point out an important difference between the slow ball here and a regular ball on a milder incline. The slow ball quickly reaches its maximum (terminal) velocity because of all the internal friction and no longer accelerates, while a regular ball on a smaller incline would slowly but steadily accelerate.
I suspected that the kinetic rolling energy had to be turned into heat somehow but I didn't think at all of a thick liquid to do this. Very cool!
Eventually, I believe the ball will start rolling faster as the temperature of the molasses increases and the viscosity decreases.
@@raelik777 yeah that would make sense but im not sure how much heat is generated compared to how fast it can dissipate
“So I have here two balls of equal weight and volume” The kid in me couldn’t help but giggle.
This gives new meaning to the phrase "slow your roll"!
I did think there was another ball inside but the molasses bit was unexpected.
Is there any other liquid which as viscous or even more than molasses?
Any mixture that is super hygroscopic. Honey for instance. But the thicker or more viscous it is, the closer you get to just a ball with higher sectional density or a wobbly ball that rolls faster but erratically because it will roll faster than the liquid can change the COG.
Tar and glass... could take eons to roll!!
Pitch is probably the most viscous liquid. They've been watching one sample of pitch drip out of a funnel at the University of Queensland since 1927.
This man needs to stop exploiting the physics engine, the server is eventually going to crash.
Fun science lesson! Thanks!
*Investing in crypto now should be in every wise individuals list, in some months time you'll be ecstatic with the decision you made today.*
I've been saying it as "it's like moving through molasses" where the molasses were just the slowness in ourselves.
"The speed is gone. Reduced to zero"
"I used the gravity to beat the gravity"
My all time favorite science professor
Great respect to you sir
Weirdly I got half the answer right when I saw how it moved like hitting the breaks at almost every pump, I thought there had to be some heavy sphere object inside it but I wasn't certain how that didn't just ricochet inside it, until you mentioned the molasses it became clear.
Quite interesting content, keep it up.

I instinctually knew it was a ball within a ball, but I never thought about the molasses lol... genius level thinking. Love it.

I wonder if there are any applications in future fields of engineering or science where we could implement something using a "slow ball". Really cool!
I got in an argument with my wife as to why one ball rolled slower than the other.
so simple, yet so brilliant.
*Interesting video. Literally half of it was a commercial.*
But thanks for filling my brain with more knowledge 🥂
Dog poops in front yard
Him: That's so coool!
I just loved how you wraped the ball in copper foil to make a lot of us fall inmediately into the inference trap of "it must have a magnet inside!". Really, that was a very smart movement.
How would a magnet do that and what does copper have to do with that
I love how he had to repeat himself to fill time for the ball to reach the ground
Nothing cooler then Eren Yeager teaching you science on CZcams

This is where magic and science meet
“Slow as molasses in January”
really does make sense after seeing this
the inner ball is perfect metaphor for the inner drive I have ,to wake up early every morning 😂
This was pretty cool. Never thought about it, but it makes all sense.
NEAT MAN! You always come up w/ a good one.
I had seen these before. It reminds me of the mighty beans sold a few decades ago. The motion made me think of a heavy object inside the ball but I never would had guessed it was suspended on a thick liquid. Interesting fact to know.
This is so interesting! I'm so glad I stumbled on this video.
i figured a weighted ball was inside but that molasses trick is very cool
I like how he says "this is so cool" but there's no excitement felt
I figured there was a ball bearing inside but I did not expect food.
Amazing experiment as always!
Please do the same with oobleck!
Okaaay I thought maybe there were pegs in the slow ball so the weight had to go around them, but this is even smarter. I love it.
Man's daughter really tied up his hair...and he didn't even care...and shooted a video....thats too cool..too much involved in science experiments 😌🖤
the smaller ball do be dominating 😩
Looks like a new Peglin orb to me
You know you are in trouble when your ER doctor shows up in this shirt. 1:11
Fantastic! I'm imagining the protons and neutrons being heavy due to the molasses of gluons, besides the relatively lightweight quarks inside them. 😆
interesting, I'm pretty sure this is the same effect that a viscous limited slip differential uses. a neat demonstration.
I've seen cheap cassette decks with a glob a thick grease used to slow down a mechanism. Like the cassette door.
It sort of reminded me of the tyre rolling up hill in an old Honda commercial (due to centre of gravity via a fixed weight), with a Rube-Goldberg machine type setup.
But I was expecting this slow all, to be a Sphero kind of thing, with regenerative breaking, which I’d assume would work too (but is way more complicated!).
I bet the optimally filled container for slowest moving would be 31.459% filled!
I almost guessed this right in the first few seconds. I assumed there was a ball inside that was itself, sticky.
Love the music, futuristic 80s vibe
The copper coating was the ultimate fake out
