What is the policy on asking homework questions on Chemistry Stack Excha...
@Manishearth I definitely know about their ephemeral nature, I just didn't know if he had a policy. What you say about whether they've been incorporated into the question makes sense.
@Manishearth Yeah, I thought it had to do with skin oils, so perhaps if someone answered in that regard it would be okay. It's a little bit of a physics question, though, if that's what you're going for
(I also assume it's due to enhanced surface contact due to skin oils or condensed water and skin oils if you try and steam it up first. It's probably not really chemistry, but I'm not sure it really fits anywhere better either.)
(Unless there's a specific "materials science" stackexchange I don't know about.)
@Aesin It ends up at Van der Wals/adhesive forces/induced-dipole/etc interactions. It's in the overlap of Phy/Chem.SE, but it's better here due to the dipole stuff
@Ashu I don't think so, the question deals with a physical interaction. The only bio-related things are the nature of the skin oils (which are biochemistry so on-topic here), and the human, which isn't really that important.
