The thing with thickening agents is that they change the flavor, even when flavorless themselves. Different thickeners have a property called flavor release, which is how easily you can taste the thing it is thickening. Some substances wont enter your taste buds or dissolve in you saliva as easily. For example gelatin has a great flavor release, but xanthum gum has a very poor flavor release. And since it impacts different molecules differently, it can change the balance of flavors. That soft drink that you are used to is going to taste weird when some of the flavors are missing. The same goes for cold vs warm drinks due to their different thicknesses. Soft drinks are designed to be drunk cold or at room temperature, a drink left in a hot car will taste too sweet and too strongly flavored (not even getting into the issue of CO2 solubility).

What i really love about your channel is that you don't tend to use specialized/expensive equipment but your demonstrations are still really well put together.

I'm so surprised how intuitively we can tell the sound difference between hot and cold water, but I've never noticed it before, only in the last few years have I intuitively realised that sound travels differently outside in the winter because of the lack of leaves on the trees...

When measuring the viscosity of paint you would get a small container with a hole in the bottom. (like a metal test tube {domed bottom} w a hole and handle to grab ) dip the container in the liquid until full. pull the container out and measure the time taken until the paint flow "breaks" from a continuous stream.

The cold water is denser than the hot which is slowing the ball. It is going through more matter, so more friction, not necessarily stickier (more viscous) matter. A really neat demonstration none the less, especially how the time changed after just a short exposure to ambient temperatures. Just a few degrees making a noticeable difference.

It may be but, just like colors, people really perceive flavors differently. Green is actually a color, a subjective property, frequency of light is not. Color depends on contexts (colors around the object, intensity of light, etc). People are not standardized machines, each person has a significantly different hardware and software (live experiences). I will not be surprised if some people can taste the chemicals, and I will not be shocked if most of them are women as some studies show that women have a better sense of smell than men.

Depending on the thickening agent, there can definite be a taste. Xanthan gum (like you've got here) is flavorless, but cellulose or starches can add a distinctive "stale" flavor to thickened liquids and food. if not mixed properly they can also leave a grainy or "bubbly" texture, due to undissolved particles and trapped air.

It’s blew my mind that i not only could tell their is a difference between the sounds of hot and cold pours but i also knew instinctively that the first pour was hot and the second actually confirmed it for me.

I had a stroke about 5 years ago and had to relearn how to walk and eat. They started me on thick water. After not being able to eat or drink after almost a month this was the best thing ever. I had all kinds of stuff that was thickened to eat to help teach me how to eat again. This was just one tool for my recovery and I'm glad it was there

I asked myself a similar question when I was in 4th grade EU (10 years old). School started teaching us swimming at that age, but the lesson was split into 3 teams, the A team, the B team and the starters. Starters were always in the warm, shallow water, and since I started swimming in warm and later got into team B, I immediately felt a difference floating. It was much easier to move through the warm water, but it also meant you sank quicker. This made it much more difficult for the starters, than it had to be. But it had the effect, that when you finally hit team B, you were more than ready, as everything became easier.

The cold/hot water pouring sound was the most intersting part of the whole video I think. That's crazy how I could instantly tell the first sound was hot water pouring. I would have never know I knew that. The hot has a deeper pitch and the cold a higher pitch, I think...

I always knew the difference between the sound of pouring hot water and cold water, but never thought about the reason. Thanks for the explanation. Amazing video indeed.

Also salinity affects the behavior of water

@@SivaranjanGoswami You are right but not only phase change temperatures are affected by salts in water, also cohesive propreties in the liquid phase are changed by salts and other solutes. For example pure mountain lake water splashes differently from sea water at the same temperature.

@lucamatteobarbieri2493 yes. That's true. That's not only salt. Anything that gets dissolved in water can affect its viscosity. Sugar syrup is simply a lot of sugar dissolved in water. Similarly, when you dissolve too much salt in water, it becomes brine.

great video as usual! always interesting topic on this channel!! may i suggest to use metric system (Kelvin or Celsius if it is easier) instead of imperial? expecially when dealing with water, farenheit doesn't have any sense.

I purchased the Kamikoto knives about 3 weeks ago. The package was shipped the day after ordered it. However, it didn't arrive after a couple of weeks so I emailed the company at 3am on a Saturday. Less than 30 minutes later I received a reply (10:45pm on a Friday in Japan!) and they sent out a replacement that same day!!! I'll update this when I get the knives and play with them.

I have no doubt that hot water is less viscose than cold, but I think one might think about what other things could possibly be happening. 1 is density change, and 2 could differences in expansion create more space between tube walls and the ball allowing water to more easilly move around the ball. The second point can become significant where expansion coefficient are significantly different and where the ball's diameter approaches the inner diameter of the tube.

@@tinhoyhu scrolling down is sort of a proxy for likes. And how far up comments perculate and get shown to others first. And besides liking the affirmation likes bring, I am also surprised more people didn't take interest to questioning an experiment's conditions.

There's also "gelled water" (and gelled solvents) for use in cleaning paintings, as they stay damp on the surface for longer (and/or with less likelihood of penetrating through cracks in the paint and potentially loosening it from the canvas), giving the water or solvent more time to break up dirt and stains or old yellowed varnish. But I'm pretty sure those use methacrylates or PVA and are def NOT edible!

From what I remember from Baumgartner Restoration, he uses laponite as a thickener with water when cleaning paintings. I believe it's a kind of clay

Very nice invention for people who have difficulty swallowing. Thanks for the video, much appreciated! On a side note, I was grimacing all through the video, although I know I needn't and shouldn't.

THis was a really good video. THanks!

my uncle had Huntington's and had to drink thickened liquids. Thickened Guinness was definitely deeply unpleasant

The only predictable part of this video was James drifting off into a side experiment and casually setting the majority of his table on fire.

Allways a joy to watch. And learn

From when I was a kid, I always wondered why coffee seemed to spill more easily, and cold drinks seemed to spill less. I thought water couldn’t change viscosity, but now I know it can.

I learned how dangerous putting boiling water in a blender can be the hard way. I really didn't think the temperature of the water would make a big difference when being blended.

Very nice demonstrations! Thanks..

Genuine question about your hot/cold water experiment: Would the temperature of the water affect the buoyancy of the marble? Wouldn't this cause objects to sink faster in hot water regardless of viscosity? Love your videos!

For very tight tolerances, you'd have to wory about thermal expansion of the metal ball and the tube affecting the results, but it looks like your setup is a pretty loose fit, so that shouldn't matter much.

@bluestormcloud791

Yes, the tube shrunk. Even a small amount would make a difference because of the narrow fit to begin with.

Wow, I always wandered why there is a difference in the sound but I never searched for an answer. Thanks.

We had to add thickeners to any liquids we gave to my father after he had had a couple of strokes. His epiglottis had become paralyzed and he couldn’t swallow anything without the risk of aspirating and taking it into his lungs. The epiglottis is a small flap of skin in the pharynx that is pushed downward when food or liquids pass by it. The skin closes off the airways while food or liquid is passing through the throat. If the epiglottis stops working, liquids and food can end up in the lungs. He didn’t seem to notice we had thickened his tea, but it doesn’t seem like it would quench your thirst since the receptors on the back of the tongue can tell liquids from solids and I would imagine even thick substances, but I guess if it’s cold enough, it can trick the nerves. I felt really bad having to put that stuff in his drinks, but the alternative was an aspiration and that’s not good at all. He didn’t live a lot longer than after that condition had arose.

I made thick beer and vodka for some elderly family once, even 90 year olds need a good night on the town.

Those water pour recordings sparked the strongest ASMR tingles I've ever gotten in my life, they're so nice. And the difference is very obvious! Hot water sounds like a long, soft exhale with lots of bubbly pinpricks, while cold water sounds like someone trying to fake a deep voice with more icy pinpricks.

Love the audio side by side. 👌🏼

I never had a science video make me laugh so hard. Thanks for posting.

In the drop test, did you account for thermal expansion of the tube? Because that could reduce the random drag on the side of the tube in the hot water.

@umbrascitor2079

To what extent would the expansion of the tube be countered by expansion of the ball, and would the difference then be significant? We're talking .2s margins here.
