I'm a graduate student in cosmology. I did my undergraduate in space engineering (rocket science). I enjoy Dark Energy, curvature, and modified gravity, but I mainly focus on inflation.

comment Why does my metalic water bottle make noise?
for instance, your rubber seal could be faulty and there might be a bit of over-pressure in the bottle sometimes so when the seal is wet air might be escaping but causes small bubbles to form at the faulty spot in the seal and as air keeps pushing, the bubbles pop with a click and tick sound. Or, at I said before, it could be the sound of expanding or contracting metal. Really, there are too many unknowns to be sure

@Abs well, more specifically, it would help if we could hear the noise or barring that, get a more informative description of the noise. A click and tick could be impact noises, popping bubbles, contracting or expanding metal, anything. Also, a thorough description of the exact circumstances would be helpful. Even with all the specs of the bottle, real-life situations are too complex for us to tell you the definite cause of a click and tick noise. We could guess wildly, but that doesn't really help you solve the problem

comment Why does my metalic water bottle make noise?
point is, there really isn't enough information to make an informed analysis without us actually experiencing the sounds and the circumstances

comment Why does my metalic water bottle make noise?
It could be thermal expansion and contraction of the metal bottle after having cold water drained and warming back up to room temp. Also could be pressure inside and out equalizing after you closed it because of this equalizing temperature

comment How fast would someone have to run to travel vertically up a wall?
@DanNeely That is certainly true for some ways of walking or running up walls, but the tendency is to angle yourself close to being parallel with the wall and walk/run on the balls of your feet. This makes the more dominant muscles in running up a wall the same as those used in climbing a ladder normally

There doesn't seem to actually be a question here. You've told us a problem and how you've approached it. That seems to be all.
