    Glass Weird
AI Thread Summary
A user shares a puzzling experience where a friend's glass suddenly broke while she was on holiday, raising questions about the cause. The friend mentioned holding the glass "on air," which could imply various scenarios, including being on a plane or simply moving it between hands. The user seeks insights into whether pressure changes during a flight could cause such an incident, but admits their physics knowledge is limited. The discussion invites interpretations and potential explanations for the glass breaking. Overall, the thread explores the mystery behind the unexpected glass breakage and the physics that might explain it.

Hi to everyone, I'm new here and this is my first post. I have been reading por a couple of days without nothing to ask/say but I have just remembered an e-mail that a friend sent me a last week.

In her mail, I don't paste it because it's written in spanish, she wants me to explain, using my physics knowledge(which is not as wide as she believes... :confused: ) something that happened to her.

What she says is that she was holding a glass and it suddenly crashed... it just broke, well she says she had it "on air" but even in spanish it has many meanings.. may be that she was on a plane(she was on holidays when she wrote me the mail) or it was just "flying" from one hand to another...

any ideas? could it have broken in a plane? some presure change?

I have thought about but my physics background doesn't suggest my any explanation... anyway she doesn't explain what happened but it open the doors for multiple interpretations and it can result in a wide range of explanations.

Let's find out what you guys think about it(I hope someone read that...and sorry for all the writing mistakes I have, surely, done...)

Ghiret.

hmm... Sniper! Are their any outstanding threats against her life?
 
Very hot hands?
 
Thread 'Question about pressure of a liquid'
I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...
I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
