#1:24 OK WHY IS THE WEST MEDIA (believed & watched profusely) ALWAYS FACINATED BY THE IDEA OF GETTING AWAY WITH MURDER? At least don't say it publicly and go consult your shrink or something......... Jeeeez!
The straw was very interesting. I expected the result when you poured water through it (shot out the end due to a lack of friction) but it go me thinking about watermains and sewer pipes. I wonder if there's a way to make the inside of existing pipes hydrophobic to increase their flow volume without tearing up and replacing the whole system?
Water flowing through a pipe already creates something similar so it wouldn't add much benefit if any. Also, it would be super expensive and no clue if it would actually stay forever or would chip off and end up in your drinking water or the treatment plants. There are some companies doing stuff with it but its still years too early to be feasible for wide use.
@@SexyEarHair There's a fair bit of friction even in plastic pipes - it's all taken into account when designing sewers (which I spent 30 years doing). As for super expensive, lasting power or "chipping off" - how on earth can you say any of this when it hasn't been invented (which is the whole point)? I'm currently pricing a couple of kilometers of Sanitary pipe that needs upsizing and it's going to cost 10-15,000 dollars per meter to replace the live sewer in place. That's a LOT of wiggle room of a "super expensive" alternative, even if it doesn't have the same lasting power as the existing pipe.
@@smgdfcmfah And water creates a boundary layer against the pipe, reducing friction for the rest of the water in the middle. Yes, there is a lot of friction. On the water touching the pipes, but the water in the middle has significantly less friction thanks to the inherent properties of water and the boundary layer. Also, Southwest Research Institute developed a process for offshore drilling to do the exact same thing already. A superhydrophobic coating to keep contaminants from sticking to the pipe and clogging it up. Different application but same theory. And how do you expect them to spend a lot more money than just normal pipes for a coating that would have to be replace semi regularly? And what do you mean it hasnt been invented yet? It literally has, its just a coating that you could spray or paint or chemically bond to the pipe. Which has already been done on plastic injection molds by the way. its not some new manufacturing marvel to coat plastic. Its just not worth it to research something that costs more money, would require additional maintenance and could possibly pollute potable water.
Lad, You have some imagination with all the different experiments and physical effects you demonstrate. Oh, and a good IQ. Cheers for all the work/research.
Using an hydrophobic knife as a murder weapon seem like a good idea but imo it's not. If they put a sample in an analyser they will find the chemical you use and they can relatively easly find who buy them and find traces at your home 😁
Could they use Ferro fluid in gold mining. Using a magnet to make the fluid act more dense than everything but the gold, and having just gold at the bottom.
I saw a video of his where he put a block of ice in a microwave. A drop of water on top ended up warning up and making a cavity on the ice. I can't for the life of me find that video. Anyone know what I'm talking about?
@iamafraidofwomen Would it help if I told you that pi is smaller than 4? Yeah you can’t write it out in its entirety, but I that doesn’t make it a large number value wise.
Boats, submarines and even aircraft need to start being made to be completely hydrophobic. The water craft are an obvious choice but with aircraft there would be no drag and no icing.
This experiment shows that air pressure does, in fact, hold water in the straw. The hydrophobic coating of the straw allows air to pass around the water, so there is no pressure difference and water flows out of the straw easily
Actually I don't think there's anything wrong about being water. Like the water droplets did not decide to become water and if they did it's nothing bad about it. Please support your water and stop hydrophobia 😔
