Title: ' New Math '
Post by MnSpring on 09/13/16 at 16:28:03

Recently, took a,  ‘Aeor-Plane’ ride.
I was in a Aisle seat, across the aisle was, (looked like), a Mom,  25 +/- old. with a 3 & 5 year old.
She had the aisle seat, kids inside.

When we were on the ground, moving into position, I noticed her drinking water from one of those bottles, that have a ‘straw’, in it, with a ,’flip top’, lid.

About 1.5 hours into a 3.5 flight, I heard, several people, right next to me, utter, VERY  excited cries.
And the Flight Attendants, rushed to those seats, and used pillows, towels and napkins, to take up the water dripping on the three next to me, and the three, just forward of that.  

I looked up from my book, and noticed she was holding that water bottle,
She was Laughing, her kids were crying, and the three, in front,
(Being Good  MinESotaEns)  Were not complaining.

Apparently, she filled up this big water bottle, after going through TSA,
Drank some, (when were on the ground),
and then the next time she opened it, we were at 30,000 + feet.

After the commotion died down, She was still laughing and apologizing, to anyone who looked her way.
saying:  “I Just don’t know what happened”.
I leaned over, and said, “Pressure’,
She looked at me and said:
 “What does Pressure have to do with this water spraying all over”.

I just went back to reading.

A 50 +year old person was sitting next to me.
He said 3 words, in 3.5 hours, they were:
    “Yep,  New Math”

After I started breathing again, I would have explained how a barometer works. And how atmospheric pressure on an open container, then closed, and opened again in a low pressure environment, would tend to cause fluid to discharge up, through the straw. You missed a teaching moment and left an innocent in ignorance.

LOLOL,  Your right.
But I don't think, ANYTHING I could have said,
would have made her more intelligent.

In fact, I, 'Think' She may vote for Hitlery !!!

And Yea, I was snickering, BUT, when I heard, "New Math".
I had to turn back in the book, to re-read, to, get back on track.

That incident, was retold several times last weekend,
And every time, it produced a  Hudge ,  'Guffaw'  ;D

(Oh, some may not know, the ground take off point
was  at about, 950' feet Above Sea Level,
and the second opening was, 30,000 +  ASL)

;D   ;D   ;D   ;D   ;D   ;D

There's a lot to be said for knowing When to explain and when to shrug and leave it alone. You were there.. and your judgement is gonna hafta be It. You're a better man than I, not laughing out loud.
That's Definitely a
Wish I wooda bin there moments..

LOL would certainly be appropriate response, but 'new math' may not be age appropriate explanation.

Probably a flat lander, never been over a mole hill in her life.
I go up 500' and my ears tell me so.

And FYI, cabin pressure is maintained below 8,000 feet... about 8 psi vs. 15 psi at sea level.
And soda pop for air flights have to be a low carbonated variety.

Well 7,000 feet of pressure was, in that case, enough to, 'wet' several people.

I think there's more to this story.

I fly once a week on average. Flew yesterday from Philly to Chicago to St. Louis. I've filled up dozens of water bottles at the airport and opened later.  The bottles expand slightly (you can feel them noticeably 'tighter')  but never to the point where the pressure differential is so great as to cause the content to spray out.

I don't know the math to figure this out, but water is heavy so the pressure necessary to move 12 ounces of water 3 or 4 feet in all directions for example seems like it would be enough to break the bottle. If in this case, it was a very high quality and extra strong bottle so it resisted breakage, that would mean your typically water bottle would leak all the time which I can promise you they don't because I fill up bottles and carry them on board all the time.

Maybe when she opened it, there was a tiny rush of air escaping, she panic and jerked upwards throwing water everywhere. Not sure, but I don't think it was pressure differential that did this.

Next time you go, take a peak at the can.
I remember it saying something about it.

Yeah, your probably right, more to it.  and besides the straw.
I'm gonna guess going from 14psi to 8psi won't double the air volume but nearly.  So if the bottle was half full when she boarded, it would then empty when she opened it at altitude.

So... make sure your bottles are full when you get on Or they'll be empty before you use them.   :-?

I wouldn't think so because you can buy cans or bottles of soda at the airport on the other side of security and take on the planes, which I've done, and I don't recall seeing anything. I'll look and report back.

By the way, one of my largest customers is liquid bottlers. It's an amazing process to see plastic bottles blown into shape and filled. The speed and quantity in which they are produced makes it even more amazing.

I was also driving past York, PA this week and had some extra time so stopped in for the free Harley Davidson plant tour. Worth going to but not necessarily worth a special trip all the way to York unless you just want a destination to ride to.

Fly about once to twice a year. Never experienced this before.

And from the responses, from people that fly frequently, I Looked, Closer at, ‘Water bottles’.

The ’New’ ones, with the, ’straw’, and the flip top, have a little small hole in the top. Like a blatter, it is closed so water won’t drip out.
But when under pressure, (or lack of) They will allow air, or something, to go through.

At the County Fair, a, ‘church’ was giving away water bottles. I was pushing around my Mother,  (She takes Any Thing, FREE)
And she left it in my car.  When I flipped open, the top, and blew into it, Air came out the little hole.

Then I went to my lawn mowers, where some have one in,  (Which is Not aways, water).  And Because they were  .50 Cent Purchases at a  Garage Sale, guessing they were older models.  And with them, I could,  blow, into the flip top as hard as I could. Didn’t bulge the plastic, but No air escaped, and when I took my lips away, the air came rushing out.

So with this, ‘empirical’, evidence, I surmise, (Did not examine it),   she had a, ‘older’, style.

Do remember, about two years ago,
The F.A.  with the, ‘Free Drink’,  
(About 1.5 oz of pop, with a glass FULL of Ice)
Just gave me a full Can of pop,
(Must have winked at her just right when I asked for a  ‘Ginger Ale’)
She said:  “Open the can  Slowly”
