I think that is an example of the Bernoulli effect.
However, there are other possible explanations. It's one of those "simple problems" that turn out to be not- so- simple.
Air pressure changes when the hot water generates warmer air, thus like the weather, wind (or in this case a small draft upwards) is generated. Air pressure and current causes the shower curtain to move as cooler air is sucked under and around the curtain.
The downward movement of the water in the shower creates downward movement in the air inside the shower area. Air flow causes low pressure and so the air pressure from outside the shower area is able to push the curtain inwards.
Many people have tried to figure out exactly how and why this happens but no one has ever proven their theories conclusively. There are 4 leading theories. The first is the Buoyancy theory. Which says that as the hot air rises, and replaces the cold air, it creates a Coandă effect which is similar to a small vortex of air which sucks the curtain inwards. The second is the Bernoulli effect. This states that the air matches the velocity of the water coming out of the shower-head and lowers the air pressure inside the shower and against the inside of the shower curtain. This results in the shower curtain being pulled inward. The third is a combination of the first two. It's called the Horizontal vortex theory. A computer model showed that the water coming out of the shower-head can create a horizontal vortex (sideways tornado) which causes a pressure drop and pulls in the shower curtain. The fourth and final is simple condensation. A hot shower produces steam that will condenses on the shower side of the curtain and lowering the pressure there. The condensation will be continually replaced causing a temperature fluctuation which results in times where net steam production is negative. So there you have it. Who would have thought such a simple thing still remains partially unproven.
When you have a hot shower steam is generated and, because it is warmer than the surrounding air, it rises. As the steam flows upwards, cooler air flows in to the lower level of the shower. If the shower is not fully enclosed, the steam will flow out the top of the shower area and the cooler air will flow in near the base of the shower. If the air cannot easily get around the curtain, it will push it inwards as it flows past. Ways to address this are:fully enclosing the shower to keep the steam inweighting the curtain basehaving significant gaps beside the curtain to let air inhanging the curtain so it is held against the shower base lip by its own weight by positioning the rail well outside (>100mm beyond) the line of the base. (This will mean that if the curtain swings outside the shower base it will drip on the floor, so needs a high lip to hold the curtain in.)This effect is caused by a small reduction in the air pressure of the column of air that is inside the shower curtain. The reduction is caused by the pressure of the water being sprayed out of the shower head having to drop from a higher pressure towards normal atmospheric air pressure. This effect is known as the Venturi Effect.The air does not quite reach normal atmospheric pressure until it gets out of the column of air formed by the shower curtain. Because that column of air is at a lower pressure than the air outside the curtain, the curtain gets pressed inwards by the higher (but normal) air pressure in the rest of the room.This effect happens the same no matter if the water temperature is hot, medium or cold.
A shower curtain is designed to prevent water from splashing outside the shower or tub area. When the water hits the curtain, it runs down into the tub, keeping the rest of the bathroom dry. The curtain typically hangs from a rod inside the shower or tub and can be easily drawn back for entry and exit.

The downward movement of the water in the shower creates downward movement in the air inside the shower area. Air flow causes low pressure and so the air pressure from outside the shower area is able to push the curtain inwards.
The flow of water from the shower creates a low-pressure area inside the shower stall, causing the shower curtain to be drawn inward due to the difference in pressure between the inside and outside of the shower. This phenomenon is called the Bernoulli principle, where higher speed of a fluid (in this case, the water spray) results in lower pressure.

Just static electricity. Spray it with warm water before you get in.Answer:The shower curtain comes in because of two factors.The shower water heats the air in the area inside the shower. Hot air is less dense than the cooler air in the rest of the room and so the denser air pushes the curtain in towards you.Secondly, if there is a gap at the bottom of the curtain, the warmer air rises to be replaced by the cooler air. The rising air exerts less lateral force on the inside surface of the curtain (Bernoulli's Principle) and the outer quieter air presses the curtain inwards.

No, the Penlope shower curtain will provide the perfect amount of privacy while keeping the access shower water from exiting the designated area.
A shower curtain is something that you hang in your bathtub or shower enclosure, to keep the water from getting all over the floor, when you shower. A plastic shower curtain is a shower curtain made from plastic. I think most of them are made from vinyl, actually.
A shower curtain is designed to prevent water from splashing outside the shower or tub area. When the water hits the curtain, it runs down into the tub, keeping the rest of the bathroom dry. The curtain typically hangs from a rod inside the shower or tub and can be easily drawn back for entry and exit.
An alternative to a shower curtain is a glass shower door. Glass shower doors can provide a sleek and modern look to your bathroom, are easier to clean than shower curtains, and can help prevent water from spilling out of the shower.
No, the shower curtain should not cover the shower head. Ideally, the curtain should hang inside the bathtub or shower stall to prevent water from splashing outside while allowing the shower head to function properly. This setup ensures effective water containment and minimizes the risk of water damage to the bathroom area outside the shower.
The shower curtain rod should be hung securely on the wall above the bathtub or shower area to hold the shower curtain in place. Make sure it is at a height that allows the curtain to hang properly and prevent water from splashing out.
