We all know, the water and iPhone are not very good friends. Therefore they should be kept away from each other.

The folks at Apple have thought about this issue and have developed a revolutionary technology, which at the moment is patent pending, which permeated liquids inside the phone to be released without not to wreak havoc.

After detection, the sensor sends an alarm to the electrodes that will lead water to evacuate them. Depending on where infiltrated water will turn negative electrodes, positive or neutral (to attract or repel water) - to eliminate water in the shortest time.
