Vehicles vs deep water compilation

https://youtu.be/Wmscb6yfU4k

It's amazing to me how many drivers think "If I go fast, I'll have enough momentum to get through," not realizing that the bigger bow wave they create floods their engine, ruining it. Imagine how many dollars damage was done at that one crossing! It seems to be an agent neighborhood because most of the cars are pretty expensive.

Almost Every Town In America Has a Thai Restaurant

0:21 There are ten times as many Thai vs Ethiopian restaurants despite similar populations - maybe because their food is better?

A conspiracy theory that the Thai government secretly funded Thai restaurant establishment around the world.

Engineering of the 787 Dreamliner

A remarkably well-informed and illustrated documentary on the innovative engineering of the 787. 

https://youtu.be/lapFQl6RezA

9:40 during testing, the plane has to withstand 50% more than it's absolute maximum weight, for 3 full seconds.  Doing so in the 787 caused the wingtips to deform by 7.6 m! 

15:18 "The fibers of the wing have even been laid in a specific pattern to tailor the stiffness of the wing...so it deforms exactly as the engineers want it to...the wing's shadow actually changes during flight to better suit the needs at different speeds, known as aereolastic tailoring." 

16:43 hybrid laminar flow control - a top-secret system that sucks air into the wing through microscopic holes to promote laminar flow

23:12 first airplane to use 3-D printed titanium to minimize metal waste generated during machining of parts

27:54 electric (vs forced air) de-icing on the wings' leading edge allows deicing without spraying glycol over the surface

The Real Reason NYC Is Always Covered In Scaffolding

https://youtu.be/lphKvTqovHs

Because NY landlords are cheap. 

2:50 a loophole for a law passed to inspect facades for loose masonry is to leave the scaffolding up permanently over a sidewalk rather than repair the actual masonry. 

And, oddly, 4:06 all scaffolding "sidewalk sheds" must be painted a specific shade of Hunter green. 

747 total engine failure, glides to safety

https://youtu.be/YYwN1R8hVsI

White volcanic ash at high elevations is remarkably abrasive, damages all instruments, sandblasts the turbines and windscreen, and then turns to molten glass inside the engine's heat. 

After this, 37:46, pilots learned to turn 180 (to exit the ash cloud) descend and slow engines to minimum thrust (to prevent glass formation at high temperatures) 

Making a 13600 horsepower Diesel Engine

https://youtu.be/w4uMX5mWAF4

11:29 the crankcase takes two full weeks to cool down after casting before it's removed from its mold. 

16:58 to clean the molding sand off, millions of 2.5mm steel pellets are fired at the casting at 200 kmph (130mph) - this also helps to harden the steel. 

27:12 each piston-connecting-rod combo (a "power unit") weighs 750kg (1600lb.)

48:25 it will operate for up to 35 years, maintenance-free.

How long is milk good in the fridge?

"it is actually best to store fresh milk in the refrigerator at 4°C and consume it within three days after opening."

https://www.sfa.gov.sg/food-for-thought/article/detail/how-long-can-you-keep-fresh-milk-once-it-s-opened

"there's even a specific location in your fridge where you should be keeping your milk — and it's not on the door's shelves...milk should be stored at 38° to 40°F in the same container it came in, and far away from the door."

https://www.businessinsider.com/when-to-throw-out-your-milk-2018-1

"Once opened, all milk can last for 4-7 days after the milk expiration date."

How Airlines Quietly Became Banks

https://youtu.be/ggUduBmvQ_4

This really surprised me - airlines loyalty programs make them so much money that they're willing to fly people at a slight loss just to keep them in their loyalty programs. 

15:15 "airlines have nearly complete unchecked control over a currency with which they are the only entity which can convert it to cash. Frequent flyer programs are genius financial instruments because it's nearly impossible for the airlines to lose."

Sand Mining - A Major Global Environmental Crisis

Who knew this abundant material was in crisis - we're extracting far more than gets produced. 

https://youtu.be/M7XVp8hADcU

Sand - the second most extracted resource on the planet, after water. 

6:15 there's actually very little regulation, monitoring, or enforcement around sand mining

We need to find alternatives - 11:45 perhaps harness the bio-mineralizing capability of photosynthetic micro algae.

For the Best Boiled Corn, Don’t Boil It At All

This channel is great for cooking tips. 

https://youtu.be/g5ABAbnTPAA

6:02 boil the water, then turn the heat off just as you add the corn. This achieves the ideal temperature to gel the starch without making it chalky it starchy, yet not too hot to dissolve the pectin in the pericarp making it soft and sticky. 

https://youtu.be/2guC4Badq2s

Perfect crisp bacon every time by adding a bit of water at the beginning. This creates the perfect temperature to render the fat without burning the meat.

3:10 less than 4% of the world's population currently relies on desalination for water. 

3:55 a new method of "temperature setting solvent extraction" uses lower temperatures than distillation requires, and temporary combination with a solvent to improve separation of salt allowing for a "zero liquid water discharge" process that avoids pumping brackish brine back into the ocean with attendant environmental consequences. 

Repair a destroyed car
