Everyone knows someone who has dropped their phone into a toilet, if they haven’t done it themselves. The problem is that electronics are not water proof. They may be resistant to water in small dosages, but after being submerged in water, or dumped on by any other liquid, these electronics are destroyed beyond repair.
The good news is that new nano-coating technology could prevent the damage that is inevitable from electronics being submerged in water. The coating is simply sprayed onto any solid surface, which will then repel almost any type of liquid.
