You made this longer than it needed to be. Anyway, I carry my pill containers there, and for the pants with larger "little" pockets, small sanitizer bottles.

I would love to find out why it is so strong. Nylon is one of the first polymers to be commercialized and has a certain kind of polymer bond. What is different about the polymer bonds of Kevlar?

Corn cobs were not used in Europe until after the crop was introduced from the Americas.

Just wanted to say thank you for the work you guys put into these videos. I enjoy watching them. Bravo!

I think the transition from carbon to alkaline batteries came well before halogen bulbs and was a huge leap in functionality!

Air brakes can still function perfectly with a minor leak. The air brake system will never run out of air but a hydraulic system will run out of brake fluid if there was a leak even a minor one.

Moooooooooooooo9

Kevlar as well as carbon fiber have been revolutionary materials….. such cool performance products made from them are now available to the world -Science delivers again!

I love learning.... subbed

So how come when a truck parks, there's always a huge rush of air releasing .

The real reason they use air-brakes is the ability to change trailers; a hydraulic system would not allow for this. Air-brakes are archaic, it’s basically the same system that trains have used for over a hundred years.

Did you notice the old can said "makes screwing a pleasure"?

I worked with sheet metal for many years. Kevlar gloves may have been the best thing that ever happened to our shop.

A guy named Kevin and a guy named Larry 😂

I sold tires and wheels for years, moving up to management, but one thing i noticed is so many peope ask us to leave the sticker on the tire when they drive out, gotta stay looking brand new😎

Good to know.😊

Good to know.😊

After watching this made think of an alternative, how did Tylenol evolve as a pain reliever and fever reducer?

I love that you called it bullet resistant rather than bullet proof.

In 2024 it's used for a condom often forgoten

Im a lucky boy my mercedes vario has air over hydraulic, twice the fun!!

Unless you are talking about the Duck brand of tapes, it's ducT tape. It doesn't quack. The only other option is, you're a moron.

The history of underwear told by a man, who jumps in one go from the early stays to the Victorian corsets in one go, and skips the part about women wearing slitted drawers. Mansplaining if there ever was one.

I had no idea the mane ingredient for smokeless gunpowder is found in paint and glue, NInitrocellulose is an amazing compound.

How one way bullet resistance glass is made?

As I recall, Opera introduced tabbed browsing.

Big trucks use air brakes to slow down and stop.

Where is it written / documented that the Romans SHARED the sponge-on-a-stick? Was there some terrible shortage of sponges and sticks in Antiquity? Were there not enough slaves to ensure enough sponges-on-sticks to cleanse the Patricians' noble backsides?

They also use air brakes to scare automobile drivers next to them when stopped at a red light.

Jeep 🚙 : just empty every pocket, i know, i bought one.

I'm sure I cannot afford bullet proof glass in my car so I guess I'll have to make my own with plexiglass layers.

At about 1:10 you say "people had no means of portable, artificial light". The Carbide Lamp was developed in the late 1890's and was used on cars and bicycles. The first bicycle lamps appeared in 1896. With the first carbide bicycle lamp patented on August 28, 1900. There was also a helmet mounted version used in mining and other industries. It would be interesting to see the market share of electric v.s. carbide during the early 1900's as Inventions and improvements to both devices continued for decades. A substantial percentage of cavers still use carbide lamps today.

And here I was thinking the codpiece was most useful as a place to hang a towel.

Can you explain the flesh light next?

I always wondered! Thanks!

The car in my thumbnail is my 2003 Lincoln Town Car "BPS" (Ballistic Protection Series) that came from the factory, not a third party, with bullet resistant glass which required modifications to many stock parts like door panels that were all made by the Ford Motor Company for it's Lincoln division. It also has many other protective features but was designed to look identical to a stock Town Car. If you think I'm joking, wait until you look it up. It's a real car! Same car they would've buried Jimmy Hoffa in if he wasn't already stuffed in a Dodge Omni...

This is my new favorite channel.

Very interesting video took my very first flight mid July from Illinois to California was awesome

FINALLY someone explains the full details of how airplane wings generate lift, well done! There is no law of nature that tells air particles on the top of a wing that they need to arrive at the trailing edge at the same time as those traveling under the wing. In reality, the air on top often arrives sooner than the air on the bottom.

I dispute your theory that the fedora was adopted by men from a women's style. Maybe the name, but not the hat. The general shape of the men's fedora was the next step in the evolution of the men's western hat or what we now call a cowboy hat, which evolved from the tri-corn of the 18th and 17th century and the men's high top hat. So was the bowler and the Mexican sombrero. Felt hats were a major reason for the beaver skin trade that moved westward as beavers were trapped out from eastern states.

Very nice explanation. Could you explain how acrobatic and fighter jets fly up side down.

nice.

2:27 It should really be called air-released-spring-actuated-brakes. The air pressure is actually holding back the spring that when released would mechanically clamp the brake pads or press on the wheel drums to stop the spinning wheels.

Why Dress in front of windows? 😊

You missed the reasons for supportive bras for women. Films had bouncy boobies in silent films and had the need for holding them still as they walked.

Greeks exercise was in nude.

It's because jews were clipping coins

Bought a $200 bidet seat a couple years ago. Once you 'go water' it is impossible to go back.

It was called a flashlight because the batteries were gone in a flash, back in the day.

5:21 Re: Corsets. Please STOP repeating the LIE that ''corsets were uncomfortable''. The whole idea of a corset was to accentuate the female figure... AND to support the torso. Any corset that was uncomfortable was one that was ill-fitted and / or poorly made. It's most likely a feminine-form hating feminist or a man who first started up the story that corsets were always overly-laced and uncomfortable.... a lie begun to enforce the ideology that females were forced by the Patriarchy to be subordinate mindless objects.
