      Hi Cai! Easy question – because it reflects the sky! Unless it is filled with heavy metal, water isn’t blue itself. Fill a jug from the sea and take it indoors to check!

      Hi cai!! Mostly it is because water surfaces reflect light strongly in blue wavelengths. Check out this great description I found through google: http://www.loc.gov/rr/scitech/mysteries/oceanblue.html

      I found it pretty interesting!!!
