Ice is a crystal structure where the bonds of the water are linked together in a lattice.
Something looks ‘white’ when it scatters lots of the light that hits it into every direction.The structure scatters light a little bit, but the most scatter happens where the ice crystals meet the air. A block of ice only meets the air round the edges, so not much light is scattered. Snow has a very intricate structure, with lots of faces so lots of light is scattered, making it look white.

@Tom: There are quite a few questions that appear in Ask just after the Chats finish. I didn’t notice this one in the chat – too busy answering other questions. 🙂
Tom commented on :
The chat is mad, I think I must manage to address only about half of the questions and I am typing literally as fast as I can (not that fast, I must admit)
Tim commented on :
Yeah, me too.
