I saw that video and it intrigues me, so I try to replicate it with straws but it didn’t work
Can someone explain how does this work and why my mini replicate didn’t work
In: Physics
In a vertical column of water, the pressure must increase due to gravity as you go downward. If the bottom of the column is open and fixed to atmospheric pressure, then the top of the column will be at a lower pressure. If you have two open-bottomed columns connected at the top, then whichever one has a lower bottom will pull more and suck water in from the end/column with a higher bottom.
I have managed to replicate this with straws, but it was difficult. Without knowing your setup, it’s hard to say what the issue was. Was the ‘output’ end of the straw physically lower down than the input end? Were several straws chained together?
