I don't think by weird the op meant "Wow, this is a miracle that can't be explained by science." It was more along the lines of "Wow, this interesting and I would never have expected that to work. And boy would it look strange if everyone walked around with their phone in a cup."
And I agree with that statement. So yes it is weird, despite the fact that it has an explanation.
- iwwr 16y agoIs this a good illustration of the phenomenon? http://i.imgur.com/cDgjD.jpg http://i.imgur.com/cDgjD.jpg The glass is the antenna and the shape (here a circle) radius at a given point is the signal strength at that point. The glass is exploiting some anisotropies(?) in the cell phone signals. i.e. the red arc is somehow bigger than the black arc. I am using the circle as a way to depict an isotropic signal. If the signal is not isotropic, the shape would be somewhat more bulged in the left region (pear-shaped). Sorry, IANAP, if someone can explain it better...

- zinkem 16y agoI think what OP is referring to is when light hits glass, some times it is reflected and sometimes it will move through the glass, depending on the angle it makes with the surface of the glass. So the signal is probably bouncing around inside the glass so the phone is able to pick it up.
