Bergy bit
The "head" on this small iceberg reminds me of a figurehead on the prow of a ship, only this one is sporting a sweat band.
The blue colour comes from light being refracted through pure ice. The whiter ice has air bubbles trapped inside (ancient air I might add, probably over 1000 years old.) If you pop a small piece of the white iceberg ice into your G&T it fizzles and hisses loudly as the air escapes.
