I think if this was tested under controlled conditions, most of the causes mentioned would contribute, but as the curtain mostly pulls in towards your hips, where the air is warmest, (imo), your answer is still the most valid. | |

| Jun 29, 2017 at 16:02 | comment | added | user154420 | @TylerH No, nothing to do with our bodies, the correct answer is given by jmac (and Steeven earlier). My answer is incorrect, my idea did not take account of rising, low density air. | |
| Jun 29, 2017 at 15:56 | comment | added | TylerH | So you are saying if we turn the shower on as we normally would and then observe the inside of a shower via a camera, rather than stepping into it, the curtain would not rise/pull up or in at the bottom? That it's our bodies (or the effects around our bodies) causing it? | |

| Jun 29, 2017 at 13:35 | comment | added | valerio | @EmilJeřábek It has been deleted. It was similar to JMac's one, though. | |

| Jun 28, 2017 at 13:46 | comment | added | YSC | I can experimentally confirm Countto10 theory about the air velocity due to the failing water, regardless of the water temperature (at least into the range [10°C;40°C]). | |

| Jun 28, 2017 at 9:58 | comment | added | user154420 | @valerio92 thanks, that's a fair point. Although, I would (half heartedly :) argue that the increase in temperature effect is something I would have to check myself. | |
| Jun 28, 2017 at 9:13 | comment | added | valerio | If the increase in velocity due to falling water was the significant factor, it should work irrespective of the water's temperature. Also, even if I haven't crunched the numbers, I think that this effect is many orders of magnitude too small to have a real effect. I think that Steeven's explanation is the right one (see comments). | |
