Instead of rice you may want to hear what this fellow that repairs cell
phones and such has to say.

I got through a couple of minutes of this foul-mouthed loudmouth before
giving up. He may have a point (although he's got a vested interest as
he repairs cellphones), but you might do better to look at a link given
in one of the comments on the Youtube video at:

However, having read through how they did that "study" I'm not entirely
convinced by their conclusion! Note also that the OP's camera was not on
at the time, which, IMHO, makes a hell of a difference.

Seems to me like they have the same conclusion that the rice is not
worth trying.
