Why does shower curtain flutter inward?

[r3dxP]

why does the shower curtain(in most showers) tend to flutter inward during a shower?

well, i know its not due to water temperature because convection due to hot and cold air is not the primary answer.. so.. i think its because the adhesive forces between the [curtain - water molecule - shower tub] is greater than that of adhesive forces in the water molecules, thus, curtain tends to flutter inward to the shower tub.
please correct me if I am wrong. thanks alot!

You had the right word - convection! Air inside the shower can move fairly rapidly (accelerated by the stream of water droplets) which lowers the pressure by Bernoulli's Principle. The pressure difference pushes the curtain inward.

You are correct in your understanding that adhesive forces play a role in the shower curtain fluttering inward. However, it is not just the adhesive forces between the curtain, water molecules, and shower tub that are at play. It is also the Bernoulli principle, which states that as the water flows past the curtain, it creates a lower pressure area behind the curtain. This lower pressure pulls the curtain inward, causing it to flutter. Additionally, the airflow created by the hot water in the shower can also contribute to the fluttering motion. Overall, the combination of these factors leads to the curtain fluttering inward during a shower.
