Macro on Monday - Guess What

First the answer to the last Guess What. Guesses of hail and sleet were close. Actually it was snow - that fine powdery stuff we get from time to time. The air temperature was high enough for it to start melting as soon as it landed.





On to this week's Guess What:

iPhone4 fitted with miniature microscope lens

Ignore the bright circle. That was the LED lights illuminating the clear plastic of the microscope.

Clue: Actual size about 5mm. Only seen in parts of the village when the temperature is around freezing, or lower, but it won't melt when the temperature rises.

No prizes. Just for fun.
