i alredy figured out the answer....
THe Question is, where does all the blue go from our water when its put into our taps... well here the answer...
all the blue taken out of the water it put into the sky.
and that answers the question of why the sky is blue at the same time....
so when somone asks you "why is the sky blue" tell them, the blue is filterd out of the drink water and put into the ski with big smoke stacks... thats why water in a galss is clear but water in the ocean is blue.
