So, wesi !! Welcome and thank you for having posted here. As you can see, we love to explore such questions. Now that we've had such awesome technical input … I have a request.
The preamble to my request is as follows:
Despite my desire to learn stats at an early age, did not have the good fortune to take such a class until I was about 36 years old. I took an 8 week accelerated class at the state university over the summer. To this day, some 15 years later, I am still awed, inspired and grateful for the teachings of my first stats professor whose intelligences included great genious in the area of teaching. He explained to our class many times… "unless you can explain what we are learning here so that a 5 year old can understand it… you haven't learned it well enough."
wesi asked:
and many answered.
Here's the challenge:
Using one single post: can anyone in our group explain the answer(s) to wesi's question in terms so simply that even a 5 year old would understand it?
Thanks.
{and yes…sometimes i feel like a 5 year old
}

I was also told that there was a limit to how high liquid gas or water would rise to fill the vaccum.
Folks, anyone know that height? Please help.

but i'd guess you'd have to start with explaining pressure and how even air has a weight that pushes down onto everything.
when you suck on the tube, your removing some of the air on top of the liquid in the tube meaning there's less weight/pressure pushing down on it.
this causes the liquid to raise until the weight/pressure of the liquid inside the tube along with the weight/pressure of the air left in the tube are again equal to the weight/pressure of the air pushing down on the liquid outside of the tube.
now because air has a max weight/pressure, this means there is a max weight/pressure pushing down on the liquid outside the tube, it also means there is a max height it will be able to push the liquid up inside the tube.
this max height is reached when the weight/pressure of the liquid inside the tube(with no air in the top of the tube, so no extra weight/pressure pushing on the liquid in the tube) is equal to the air weight/pressure pushing down on the liquid outside of the tube.
now could my 5 year old understand that?? i've no idea she's 19 now, but i'd guess it would depend on how well i explained pressure to her..
