Hi All

An illustration that stuck in my mind...

I once replaced the roofs (outer covers) of a whole apiary, with ones that
had brand spanking new 'Spangled galv' metal covers.

It was quite comical to see the bees flip upside down as they flew over
them. most crashed, but some made it to the other side and flipped normal
again.

I put this down to reversal of the polarisation of the light, caused by the
reflection from the shiny surface... would snow also do this polarisation
reversal?
