Crisps are Flammable...
Next time you need to light a fire, make sure to have a bag of crisps close by. Surprisingly, the go-to snack is both flammable and non-toxic, especially those powdered with seasoning. Interestingly, crisps that are powdered with cheese are extra handy as they will burn for a longer time. Definitely remember to bring bags of crisps on your next camping trip.
