Lighters and matches are the most common methods used to light a fire in the outdoors. However, here is an amazingly simple technique to create flame if you have a need.
Only the (silver lined) wrapping paper of chewing gum and a battery can become a type of lighter to ignite a fire.
▼A Common AA battery
▼ The (silver lined) wrapping paper of chewing gum
▼ Cut and fold the wrapping paper into 3 equal pieces approx. 2mm wide
▼Place the silver paper onto both ends of the battery
It will quickly ignite into flame
Toss the flame onto a crumbled newspaper to maintain the flame.
Be careful not place the silver paper or any batteries together nearby within the reach of small children to prevent an accident taking place.
