You keep releasing your Hamon through your palms, creating a burst of Hamon. You want to release your Hamon from your fingertips so it will hold the water.
lol nice I think instead of this device u could make 2 holes in the top of the cup and put a string through each and hold it like that. That way you don't have to 3d print anything lol
We have been using it for hundreds of years in Turkey. It is called Turkish tea serving tray or better to search with local name "Kahveci tepsisi". It holds a lot of tea glasses and prevents spillage, therefore tea and coffee has been served in them for a long time in here.
This is, amusingly, exactly how I carry my travel mug without spilling it when I don't want to wash the lid. I just hold it by the top by three finger tips and let my hand more or less swing free as I walk. The same effect is much harder to get holding a coffee mug by the handle.
I've intuitively done this for years especially cereal bols and I've never spilled any even in the dark. That's cool to know why I thought I just had good balance
So maybe that's why waiters can carry drinks on a tray balanced on an upturned palm. Their arm may be acting as a reverse pendulum so that the tray is not oscillating in harmony with the waiter's steps anymore. Very interesting. By the way if you walk backwards with the coffee cup it is also less likely to spill as your natural tendency to use you arm as as counterbalance to your steps doesn't happen so much in backwards mode. Of course on average you'll spill a lot more coffee this way as you trip over your furniture ;)
Awesome! Now I just have to train myself to walk backwards all morning with my coffee! This might catch on at the office and we'll all have backwards walking mornings.
You can do this in a bath full of water. When I was a kid, I found that when I rock my body back and forth with just the right frequency, all water will eventually wave wildly until almost spilling. Finally I see the science behind this :)
When I was a teen, I took a small "paddle board" at the local pool, and somehow found a resonance to a wide but shallow warm-pool, deliberately. It was about 15 metres long and 5 wide, maybe half metre deep. I was astonished that after a few minutes of pushing the water back and forth, the whole pool sloshed (barely) centre-to-edges lengthwise. It wasn't busy there, and it kept doing it noticeably for almost a minute after I stopped. Hardly anyone noticed though. But I thought it was pretty cool at the time lol.
I love to walk spinning around in circles when I carry drinks too but never understood why my cups always arrived half empty. Thanks to you I not only see what the problem was, but I get to drink more coffe than ever!
After my Fluid Mechanics 1 frenzy I had run out of disposable cup covers and faced with dilemma of which cup style was the most spillproof I concluded a thin and tall cup would develop a lot less potential energy during a horizontal acceleration and hence less pressure on the side walls. Pressure can also be expressed as mm of water column so you if you actually do the math you get a direct reading of the wave height for each acceleration vector and cup style you choose. Though your equation shows a different property (and is a ton easier to solve), while my approach focuses on the sudden and violent horizontal accelerations transmitted from my car's cupholder.
James, you're like an angel of science. You show young minds all of these seemingly magic things and they fall in love. That's what got me interested in science at a very young age. We had a presenter come to my 2nd grade class and show us a bunch of fun experiments. Among them was a banana frozen in LN2 and used to drive a nail into a board. :) It was magical and I've loved science ever since. I'll never stop pursuing it.
In terms of circuits, the sloshing technique is like turning a positive feedback into negative feedback. This ensures that the system is stable…when with bounds. Thanks for the video!
So when you ask someone to bring you a drink in a coffee mug, make sure they have that special device and that they are not a spinner walker! Way cool at the end with the screen, Awesome!
So, where are the Unspillable Cup? Yes, there are solution how to not spill, but this is not Unspillable Cup, this is tool for carrying a cups... I was expecting a mug with a special shape. For example, a mug that has the upper edge bent inwards, so that the generated wave would collapse into the center of the mug...
I learned from my dad at a young age that walking with a relaxed loose grip makes it much easier to avoid spilling than trying to focus on not spilling it.
You could also add baffles to your cup. This effectively reduces the cup's radius into a collection of smaller radii. Then the frequency of your walking never adds enough energy to the system. Of course the best way to stop your cup from spilling is to add a lid.
Yes. Theres a book called rendezvous with rama. Its about a giant ass spaceship. Its cylindrical. At the 'equator' theres a body of water inside. It was called the cylindrical sea. An annulus of water about a kilometer or so wide. One shore was about 100 meters above the water and the other side was 1000 meters above the surface. Fore and aft respectively. This was so that while the se was liquid, when the ship accelerated, the water would have some slosh room aftward. There were also antislosh baffle structures under the sea so that directional or rotational changes causing sloshing would be mitigated. Its pretty cool.
OMG That is sooo true. There is one video that I found where he started with alright but I just noticed that he always starts with "Okay, today I going to ....."
7:23 So.. what if you stop that thing instantly? Or you're walking and that things stops instantly... Or what if it's going straight up and down fast? I'm sorry, I just wanna see it spill. 😂😂😂
I love resonance! One of the best things about being a sound engineer is understanding resonance. It helps me understand things in scientific fields too. P.S. Thanks for the vid. Always love watching your videos. Very informative and entertaining too. :)
If u install separators inside the cup,frequency will be much higher and it won't slosh. This is used in trucks that transport fluid so that the trucks don't tip over in corners or on highways
Just cut two plastic sheets about the inside profile of your cup, and a slot halfway up in one, and halfway down in the other, then interleave them to make a cross (viewed edgewise) Place this in the cup and try your drink. They probably won't seal well enough to warrant making more slots or holes in them, but you can if you want.
I love this channel because it doesn't just warm up old tricks but creates interesting unique content AND keeps it scientific. Rare nowadays - keep it up :)
Noone is going to believe me but I can already do this well enough with my hands. I have very flexible wrists and good object permanence so as long as I'm looking at my cup directly I can compensate with the direction of the wave.
I do that when carrying a full bowl of soup. Sort of like active noise cancelling headphones :) But for cups I just hold it by the rim and relax my wrist so it can swing freely like the device in the video. Totally passive, no need for attention.
Could you also design a coffee cup that has baffles in it? De-tune the cup lol. I believe speakers need weights added to avoid resonant frequencies being hit. Similar idea.
Thank you. Now I know it was not my fault that I spilled the water in that bucket as a kid. All these years I have carried the burden of failure. ;-). I got over it
Okay you probably pissed off a lot of magicians cuz you just gave away one of the secrets with the glass and water when you tipped it upside down in the water didn't come through I seen a lot of magicians do the exact same trick and now I know how they do it thank you action lab lol
You don’t need some fancy tool to stop sloshing. You can easily do it with an intentional movement of your hand. Do a figure eight movement with your hand. When you get it right you will never spill again and it’s the easiest motion to learn for this.
The way I stop spillage is by stirring it whilst I walk. I'm able to walk faster and the spinning dampens the back and forth waves. But a coffee mug like this is friggin amazing. I want one. I would love to walk down the hall worry free of spillage.
