This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

When we suck water from straw first we basically decrease the pressure inside the straw but the pressure outside the straw remains $1atm$ . So water rises inside the straw up to the level to equate the pressure inside and outside the straw. As the pressure outside the straw is $1atm$ and the pressure inside the straw is $hdg$ where $h$ is the height of water inside the straw. So $1 atm=hdg$ . Just find $h$ (be careful with the units).:)

Nice explanation , i too understood it

Another but same -

By sucking the water we are decrease the randomness of the molecules ( as it will get more time to oscillate between 2 points), now as you said , for achieving the equilibrium state water rises.

Which of the solutions did you have trouble understanding?

Once you clarified your doubts, can you help others out by writing a solution that they can understand easily? Thanks!
