Ridges In Audio Jack
How come audio jacks have ridges? There is more to them than simply preventing the jack from falling out. The material in the ridges actually lets the wire stay put. On top of that, it dictates which part the music should get channeled into. One bad is for the right headphone, the other for the left.
Silica Gel Packets
What are silica gel packets for? Normally found in shoeboxes and purses, they actually help the item stay clean and fresh until you begin to use them. They come with a “desiccant” that keeps moisture out. They absorb up to 50 percent of the humidity in the environment! Use them for your soaked phone.
