18. Cell Phone Fire
When you’re in the middle of nowhere and need to start a fire, chances are that you may struggle to do so. Yet you’ll likely have a cell phone on you. If you have an Android, you can pull out a battery even if it is not charged and open it up. When the battery is cut into and exposed to the oxygen, it should smoke up and help you start a fire.
For the iPhone, you cannot remove the battery from most of them. But if you’re not partial to the phone or near an upgrade, you can take a knife to it and open it up to have a similar chemical reaction. However, it is often harder to do this with the iPhone over an Android.
