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?

Ja*****:

1:11 the quality went from a 7.5/10 to a 1/10 in an instant

De************:

6:14 Everytime they look at each other they look away

sa********:

4:57 close your eyes and just listen. Thank me later.

Ko******:

0:45 me after telling her how big it is

Ce**********:

2:20 He's got his Grandma recording

Me****:

Me and me friend coming up with dumb ideas when we are blazed at 2AM 00:02

ar******:

"I don't want to get up"

(Goes and gets a bunch of straw and cokes to do experiments)

To************:

Why dont he just cover the straw with his thumb so it will stay

Fu******:

so technically the atmosphere is pushing the liquid into our mouths

Ab*******:

"That's what they said in the hardware store"

Zi*********:

that's not a straw

it's a pipe .

Jo********:

Who in hell actually drinks out of a bottle with a staw????

In**********:

Video: published in 2012
Most of the comments: published in 1 day - 3 months

Er**********:

so... what happened with the tennis game? :(

Mi**********:

Thanks YouTube algorithm

Ya******:

My gf would be great at this!

El***********:

why not just take a cooler to the room you are in and put the coke in it....

Sk**:

Or maby just move the fridge to upstairs.

Ia*********:

Nigel officially sucks more. Congratulations Nigel! 3:53 Nigel's mom is so proud of her little boy

Ko************:

can't go downstairs becuase the game is on. shuts off the tv for doing weird experiments with dumb straws. Legit (y)

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

I love these heterosexual experiments.

We**************:

I want to become a scientist. I'm so excited. I'm 29 and am doing a career change. I'm working on pre-cal right now and in 1 1/2 months I hope to be to calculus!

CT****:

But how does a giraffe work?

da***:

This video sucked

Ro*************:

World's longest S U C C

Al*********:

s u c c

ic****************:

Literally used to be my science teacher

Th*************:

Derek looked like he was pretty high at the beginning of this video

Br***********:

Pretty sure my ex could do it.
Or anyone currently in the US congress for that matter...

Xe******:

Man... "sucking" jokes never get old in science, I swear. It's funny every single time.

JS***:

Title should be
“Can a tube TuBE????”

Ga************:

I got an ad about too many straws in the ocean

Br*********:

The actual height you can suck water up through a straw (assuming capillary effect is negligible) is 10.0 meters. The thing that was missing in the equation at the end of the video is the vapor pressure of water. You can't get a true vacuum that is adjacent to the free surface of water. As the pressure decreases, the water will vaporize and stabilize the pressure. At room temperature, this is about 3.169kPa. The final equation should be modified to (101325-3169)/(1000*9.8)=10.0m. This is known as Net Positive Suction Head and is used quite extensively in pump calculations.

Ye*****:

If you had a long enough straw, you could only suction water upwards the length of 10 meters. After that water spontaneously boils

Ba**********:

I'm super late to the party but theres one small issue with your theoretical calculation. (Please forgive me if someone else already mentioned this) But there is an additional limiting factor on vacuum pulling a liquid known as vapor pressure. For any given liquid its vapor pressure marks a point where if the pressure on the liquid drops below that point the liquid will simply start to boil rather than expand upward. The means a perfect vacuum is impossible so the pressure difference will be less than assumed in this video. Water has a vapor pressure of 2.4kPa so its theoretical maximum height would be a function of (atmospheric pressure - max(vapor pressure, applied pressure))*g*h.
It only makes a few % of difference with water but for some liquids it's a pretty massive limiting factor.
So fun video though!
