This time, I will review the popular YouTube videos.

These days, even if it's good to watch on YouTube, sometimes people skip it or don't watch it if it's too long.

When you watch Youtube, do you scroll and read the comments first?

To save your busy time, why don't you check out the fun contents, summary, and empathy comments of popular YouTube videos first and watch YouTube?

Ja********:

0:37 his accent came back for a second

Ko*****:

0:39 Derek's accent climbs out of the woodwork

Je*********:

2:33 such a cute reaction

ma***********:

0:18 - plunger changes from up to down
0:50 - plunger changes from down to up
2:11 - plunger changes from up to down
2:20 - plunger changes from down to up
Sneaky editing, very sneaky :P

PK******:

0:19 :DDD

Em***********:

2:24 Holy buck that was such a cool sound. (Or should I say, hot? DUH HUR HUR HUR)

br****:

1:53
These guys are going to hook up...

sa*******:

Lol i just caught that there is camera cut at 2:13 b/c the mike switches hands

iP**:

2:10 dat plunger based editing

pi******:

1:38
Veritasium: "He's more like Nigella Lawson, lets face it"
Nigel: "That's a good plan... I wish"
I. WISH.

Ar**:

That's why you don't want to slam her too hard. She will ignite from the inside or at least that's what she said.

Ar*********:

In bushcraft we call theses fire pistons.

An****************:

Mantis Shrimp!

Ma*********:

Temperature isn't caused by the number of collisions with other molecules as was implied by saying that it was caused by molecules being closer together. It is because you are doing work on the molecules and increasing their speeds. Conceptually, this transfer is caused by the fact that the plunger is moving downward so when molecules hit it, they leave with a greater speed.

Fl***********:

My thermodynamics professor did this demo for us (: so fun

JI****:

diesel engine

ac******:

that's how diesel engines ignite fuel without a spark plug.

Ni****************:

It"s also called a fire piston

El********:

LMAO the chemistry between them

so*******:

This is the principle Diesel engines were built upon.

Do******:

yes..this is how diesel engines work...

Ke*********:

wow im really late. a thousand diesel enthusiasts saw this already before I got here.

Et*********:

This is exactly how diesel engines work.

Sk*****:

Isn't this the thingamajiger that causes the bottom of spacecraft to heat upon reentry to Earth? 

Ur******:

This is certainly the first time that I actually understood the concept of compression heating/not heating gas in thermodynamics! Thank you Derek and Nigel!

Ja********:

pretty much sure the dude is high.

Jo*******:

This is slightly inaccurate. They fail to mention that plunging also increases the partial pressure of O2 in the chamber, which lowers the temperature at which combustion occurs. In other words, the cotton is igniting at a lower temperature than it would ignite at ordinary atmospheric pressure.

An***************:

is this similar to how a diesel engine works?

Ca***************:

Fire pistons are old tech

ca********:

"There's some corton wall en dere"

tG************:

Adiabatic compression.

St****:

I love it, how the algorithm has brought me here after 10 years :D

Kr*******:

Published in 2011 but watching in 2019.

Co*************:

Random question..
Pressure changes the 'boiling point' of a substance.
Does it also change the auto-ignition point?

Sh*********:

And that, ladies and gentlemen, is how diesel engines work!
Of course they have fuel heaters and glowplugs(for cold starts), but the general idea is the same.

sc*******:

Now put some diesel in there and lets see that thing explode

Bl*************:

This feels like a school project and he is infront of the class presenting something and the teacher is on the side helping him what to say.

De******:

I expected to see him hitting the shaft at an angle, breaking the glass and then the glass fully piercing his hand.

I was disappointed.

El******:

A HANDHELD MICROPHONE truly this is the distant past

lo********:

If I'm not mistaken, this is the basic concept behind a diesel engine. I remember when my father first started teaching me about diesel engines when he would bring me on the tractor trailer and show me how to use it, and this very thing was what he showed me. He explained it in conjunction with the 'glowplug' when we had to change them out one winter. Because the engine block is so cold in the winter, the motor has heating rods in them to help warm up the engine so that when you turn over the motor (with the electric starter) the heat doesn't get absorbed by the engine block which doesn't allow it to accomplish an "adiabatic compression".

I remember being so blown away by it. Like it altered my perspective of science. Of course I was only 12 or so at the time.

There was all sorts of science to learn both on the farm and on the tractor trailer, and my father was never short on explaining it all.
