Twirling cell phone battery

    A lot of times, we are stuck out in public without our phone chargers handy. This leaves us vulnerable especially when we need to make an important call.
    This idea about a twirling battery is really cool. The concept is to simply twirl the cell phone battery around a finger a few times for a quick bit of juice to send a text or make a call. 130 twirls will give you approximately two minutes of talking time.
    The same idea could also be applied to batteries for other devices.
