Wild Survival Tips-you may not know a firing method: Cola cans + chocolate = fire

You may not know a firing method: Cola cans + chocolate = fire. Write it down, maybe it would be a great help to you if you were in the field and just didn't have a lighter.

We know that the bottoms of cola cans or other beverage cans are concave, so that we can use the principle of surface concentrating to get the ignition. But the general bottom is very rough, and have to play on the production date such as codes, seriously affecting the spotlight effect.

At this point, if you happen to have chocolate, it's a big use. Because chocolate can be used to polish the bottom, the more pure the chocolate the better, so do not recommend the use of sugar pulp chocolate.
