Fun fact: WD40 was never patented. A patent filing would have required disclosing the ingredients and Rocket Chemical didn't want to do that. So they chose to not file a patent and to keep the exact chemical composition a carefully protected trade secret.

Years ago, I worked in a large warehouse complex and admin building. I accidentally sent the executive prints toilet paper 🧻 to the ordinary warehouse washrooms, and the cheap nasty 🤮 brownish toilet paper 🧻 that even had splinters in it, to the “executive restrooms”. This did not go down well. When the bosses tried to retrieve “their” executive prints, the common workers had already made off with boxes 📦 of them. Needless to say, I was never promoted, but with a little luck gave some executive * (you know whats’) suffered a rough time.

She should have named it Stoudt Tape because she earned the notoriety.

Our factory produces similar scissors

Those Coloured Liones on Tyres are just to make themn feal new, just lyke the per-Fumes thay be putt into themn Týrés

good brooo ❤❤❤❤❤❤

Maybe you should be able to buy custom tyres with coloured rubber so you car stands out from the crowd?

I might be wrong but I always thought that the first pencils were named ‘Kor-I-noor because the difference between the carbon atoms of graphite & that of diamons are almost the same except that diamonds have one more atom that makes it hard, & that Kor-I-noor invented their pencils in the same year that the K-I-N diamond was found…the hexagonal shape of pencils is due to the hexagonal shape of the arrangement of atoms in both diamonds & graphite. Again I might be quite wrong.

As for Mr& Mrs average 4wheel drum brakes would be fine or dis &drum brakes woy be fine

I My self I have 4wheel disc are just more supiere

Gorilla tape is much better. Much more adhesive and lasts longer.

Another great episode! My mom had Singer brand sewing scissors that had blades which could be removed from the handles like the first sewing scissors you showed. I never figured out why. If it was so the blades could be sharpened or if you could change the blade type. I'm guessing the latter but it brought back a nice memory. 😊

Thank you! Super useful video

Loving these videos. Scratches that perfect itch. However, you are really pumping these videos out and I can’t keep up! 3 vids a day is a lot!

I enjoy this content very much. I'll probably do a marathon of your show pretty soon. Thanks!

In the '70s we all smoke cigarettes so I simply used it for my lighter.

When I started elementary school, the pencils issued to first graders (no kindergarten where I lived back then) were slightly larger in diameter and fully round, had no eraser, were painted blue, and had a thicker graphite core. Progressing to the standard yellow pencil was an achievement.

I had heard that at one time, the bright yellow was due to lead chromate (which is yellow) and that was why they were called lead pencils. I had my doubts.

Interesting. I figured they were to check alignment but also for roundness, but that was just a guess. Thanks for this video.

If the tire has no hair, it's bald... Nobody is going buy brand new tires if they're bald, are they?

Holy crap! I’m about to start my fourth year of mechanical engineering undergrad. This channel is awesome!! It has the informativeness of those old discovery channel documentaries but with a modern flavor and quality. I’m glad channels like you exist :)

The wood that goes between the paint and the lead is not mentioned here. Nearly all pencils worldwide are made from incense cedar, a species that grows in California's Sierra Nevada Mountains. I did a bit of research on artist-grade pencils and found out that there is a huge range of pencil quality and materials -- it's an interesting experiment if you can get a variety yourself and do some testing.

Thanks for having some left handed people in the video. The number 2 pencil is the bane of pencils for us lefties. The soft lead smears as our hand passes over what we have just written.

You might could have mentioned how fire hydrants have pentagonal or 5 sided wrench bosses, so they can't be opened with ordinary tools, they take a special wrench.

Yellow was probably a world choice due to the fact the bright colour could easily be seen, if the pencil were misplaced.

Thanks!!!

#Persians are much older than Egyptians, Greeks and Romans even though all three were Persian or Aryan Scythian race too. #Persians are first known people in the history who invented underwear and pants when Greeks, Egyptians & Romans wore skirts. Please teach true history.

In the USA, the yellow pencil dominates, but this is not true in other countries.

Never mentioned the women's slip of the 70s

I love that they also include men's underwear evolution

Where did we get #2 pencils and what do those numbers mean?

Excellent video, but the music is obnoxious and unnecessary!

First but certainly not last!!

Pencils need to ditch the pink erasers. All those do is tear up the paper. Years ago I tried the white erasers. What a difference. I never use the pink ones any more.

Yellow pencil evokes old school days.

Something I don't understand, wet hydrants in cold climates will freeze in winter. Hydrants in my part of the U.S. are all dry down to the water supply line. They have a drain hole that allows water to drain out and prevents freezing. When the valve is opened you must turn it completely open to seal the drain hole. The side holes are usually used by contactors using a portable water meter, for such as suppling water to a job site or filling equipment. Fire departments will hook to the steamer connection then to the pumper which will raise the water pressure going to the hoses. All hydrants here are painted silver and if you see them anther color other than silver, they indicate private lines, usually in a commercial complex or some other private property.

Ironically, in China most pencils are not yellow.😂

Serial Killer Credo: "Duct tape is silver, but silence is golden."

Suggest add to discussion cold freeze protection. Note also there is no universal diameter thread pitch for hoses. Early cities adopted their own standard. Mutual Aid agreements between departments include adapters for differerent styles.

In Wisconsin, they used to use a white strobe on top of the bus

Using toilet paper is unclean. We are not living in the middle ages. Modern homes should use manual or automatic water flushing.

Next week….why are none of my pencils coloured yellow

How comes I never came across this channel?

Lead makes a good pencil.

Would like to have known how they prevent hydrants from freezing in the winter months.

Shitty…….

0:35 This is The Netherlands, we do not use tiles on the ridge of a thatched roof in England.

I've never seen a wet hydrant. They're all dry hydrants with the valve below the frost line. It gets cold here.

Nuns taught me how to write, first using pencils and then progressing to fountain pens, I owe them a lot.

Air brakes were introduced because air is everywhere, you cannot run out of air. (if we did then we'd all be dead and brakes wouldn't matter).
