Is it true that the shower curtain effect, where the curtain billows inward, is caused by a pressure drop from airflow around the shower stream?

Yes. A reference article on the shower-curtain effect states that the most popular explanation is Bernoulli's principle: airflow driven by the shower stream lowers pressure on the inside of the curtain, causing it to move inward. The same article notes the cause remains debated, with a simulation instead attributing it to a vortex.
