Ridges In Audio Jack
You might not have even noticed this, but the ridges in audio jacks are there for a specific reason other than so the jack doesn’t fall out of the port. In fact, the material making up the ridges is used to protect and keep the wires in place and keep them from breaking while you listen to music. They also dictate which headphone the music goes to. One band is for the left headphone, one for the right, and one for both.

Silica Gel Packets
We usually see these packets inside a shoebox or a brand-new purse and know they’re meant to keep the item clean and fresh until you start using it. Have you ever wondered what’s really inside? The stuff inside is called a “desiccant”. It means that it helps keep moisture out. In fact, these little packets can absorb as much as 50% of the humidity in their environment!
