  • I have not scanned the article over at Scientific American. I says that "The vortex rotates around an axis that is perpendicular to the shower curtain." The ARD say its parallel to the water stream (and therefore parallel to the curtain).

    Hm, the whole thing really seams to be not really well covered.

  • reading wikipedia, it seems that I hadn't understood the horizontal vortex theory to its fullest. Wikipedia reads that the vortex in itself has a lower pressure in the middle.

  • A German science show says the following:

    Theory 1 is false: Hot water rising up, making cold water come up from below the curtain. Proof: the effect occurs with cold water.

    Theory 2 (=your theory) is false: The air is fast, so Bernoulli lowers the pressure. Proof: air speed would be considerably higher near the water. But one finds: It doesn't matter (as much as expected) how near the shower is to the curtain.
