Check out the video below from Buzzfeed! It shows you how to wrap up cords (and not have a messy situation afterwards), how to use your car remote, how to test if a battery is still good, and how to utilize your computer's keyboard better!
I tested the headphones taking pictures part, and it totally works! (as you can see above) I also tested the over and under theory with wrapping my headphones, and that totally works too! -Shanna
