Yall are all wrong. If you don't believe me, run the shower with nothing but cold water....and heavens to betsy, it still pulls in.
Here's what is happening:
As the water is shooting out of the spout, is causing an imbalance of air pressures between outside and inside of the curtain. The air on the outside is pushing against the curtain at 15 psi (as it pushes on all things at sea level from all directions). Because of the moving water, it is creating slightly less than the 15 psi, causing the curtain to be pushed into you.
As air passes over on a object, it lowers the air pressure on that side. Have you seen a convertable top on a car going down the freeway? Notice how it is bulging up? 15psi inside the car, less on the top of the top. Ever notice how your car pushes in towards oncoming traffic as it passes by on a highway? 15psi pushing on the outside lane side of the car, and the one passing. Notice how it's more pronounced as you pass by a tractor trailor?

A cloth shower curtain billows less. You can also get shower curtains that have magnets at the base.
Here's what is happening: the hot water is warming the air. It becomes less dense and rises out the top. Cool air from the room rushes in to replace the air, causing the curtain to billow inward.

The air in the shower has lots of moisture and is thus less dense than the outside air. It rises, and is displaced by outside air, which moves the shower curtain. You can put weights on or in the bottom of the curtain to reduce this effect. (Technical detail: M.W. of water vapor, 18, M.W. of air, 29.)

I know I know!!!
When you put hot water in the shower, it heats up the air... Hot air rises... leaving a 'space' for cooler air to come in... but, it can't come down from the top... oh NOOOO, it has to come in from the bottom... moving the shower curtain as it sneaks in.
To stop this dreadful condition, heat up your bathroom to 140 before hand, or get a fabric curtain, or glass doors, or just live with it like I do

Warm air rises. Creates vacuum underneath. Cooler outside air sucked in. Curtain moves. Try a fabric liner instead of vinyl.

Your shower's flow can be studied by Fluid Dynamics. If we take the flow as Ideal, (that is, no rotational character in it) then there is something called Bernoulli's equation in the subject which analyses such a motion. (Please go to wikipedia and find more)
This equation tells us that: The pressure part depends on the gravitational part and velocity part of the flow. Thus as velocity of flow increases, the pressure part decreases. Hence, the curtains move towards the low pressure side.
Please go to wiki for more.
P.S: If you like the answer, please rate it as the Best.

does not say hate, yet... I actual have a cat spirit, and getting moist on purpose isn't some thing i might do till it is mandatory... ok it feels good AFTER the bathe -till it is totally chilly exterior, considering the fact that i exploit chilly water because of the fact warm water makes me sense like I actual have a fever or some thing...-, however the bathe itself... no, i do no longer think of so.
