So this gets me thinking (although laughing at the same time because it seems
so silly) can the fresnel lense in my rear window cause a fire when combined
with the California sun? (the fresnel is that 3M fisheye lense that sticks in
the back window and keeps you from backing over your nephews bike.) Or is it
the exact opposite of a magnifying glass so it would diffuse the light?
