What are some natural ingredients one might stumble upon in the wilderness that you could potentially mix together (sans laboratory) to create a flash or explosion?

For a story-- I'm not planning to blow anything up. :)
Wood ash or pine sap or animal dung (fertilizer) are all examples of the kind of combustible ingredients that could be found in the great outdoors, and that might be used to create a small flash or explosion.
What combination of natural ingredients could (however improbably) make this happen? If I have to resort to gunpowder I will, but I'd prefer to avoid it.
