Google's Winter Surprise: SnowFlake

 Search engine giant Google rolled out a magic word for its users. If you typed in the words 'Let it snow,' snow flakes started gently falling from the top of the screen. where all of a sudden a snow storm hits the screen on typing 'let it snow'.

Another coolest Google search trick is if you type  "do a barrel roll," which produces a clockwise rotation of your page.
