Unlike some videos that are circulating your Facebook feed, this one may save your life someday.

We’ve all seen plenty of survival shows to know that starting a fire in the wilderness can mean a difference between life and death. The most common way of making fire when you have no matches is by rubbing two dry sticks together, but it is labor intensive and sometimes finding dry wood is impossible so this guy found a way to make a battery out of lemon and some hardware and then shorting it out.

Even if you don’t plan on being stranded in a jungle, this is an awesome chemistry lesson. This is so cool. There is so much out there that I don’t know.

Science and chemistry are very exciting to me and I wish I would have paid more attention when I was in school. 

Don’t hesitate to share this cool stuff with your friends and family who like science…

THE END!!!!!!!!!!!!!!!!!!!!
