How does such a simple device defy the laws of gravity? (And light)
>>16803391In what way is it breaking either?
>noo is that refraction!??????>im losing my mind help me science!
>>16803394>>16803417t. doesn't understand science yet
>>16803425Not answering the question is doing nothing to clear you of the charge of gross stupidity.
>>16803394Explain how water goes UP the straw. (You can't)
>>16803474surface tension
>>16803475Take notice of why blowing is possible (you push atoms out of your mouth which then push whatever you are blowing), and then try to image the reverse of that, sucking in. Its not possible. What, do the atoms wrap around the object, and then reverse direction to pull it in?
>>16803482
>>16803482The liquid below the volume that you are sucking exerts pressure on it. By sucking in air, you remove the pressure working against the pressure of the liquid, causing it to move.>Er... how do you suck in the air?!<You will take your meds, and you will not investigate further!It's actually because you are expanding the volume of your lungs due to movement performed by your diaphragm, thus allowing for air pressure to push air into your lungs.
>>16803521>actually because you are expanding the volume of your lungs due to movement performed by your diaphragAAAA YOU NOGGERJU YOU RUINED BREATHING FOR MEEEEEE AAAAAAAASASS
>>16803482They can reverse direction because they have negative charges picked up from the air (negative, cold environment) relative to the lungs (positive, warm environment)
Why the fuck does water fall out of the glass when I turn it upside down?The hydrostatic pressure doesn't exceed atmospheric pressure unless the column is over 10 meters tall so the air should keep it in the glass.
>>16803391naive realists be like>behold! the straw was cut in two!
>>16803816Because there are equal amounts of atmospheric pressure on top of and below the water cup, they cancel out, and, at the initial time, you are only left with the hydrostatic pressure.
>>16803521>It's actually because you are expanding the volume of your lungs due to movement performed by your diaphragmI just tried drinking through a straw like this and I'm still choking
>>16804204Meant for >>16804005
>>16803391It's just a lens
>>16804204No you stupid faggot, the air pressure on the top of the upside-down glass does nothing. It falls out because of the Rayleigh-Taylor instability at the air-water interface.
>>16805269>made up terms
>>16803474>(You can't)light travels slower on water.
