If you're stuck in the wild and you need some awesome tinder try some milkweed down. That stuff is verging on explosive.

In fact, some wild plants ARE explosive. For example the pollen of 'wolf's paw club moss' has been used in flashbulbs. I digress, milkweed down is one of the FEW wild tinders that will even start from the FEEBLE spark of an empty bic lighter.
