The Taste of Water

Ok, so I was walking today and I started to think... how do you describe the taste of water? Really, have you ever thought about it. It's not sweet, sour, bitter, or spicy; so what do you use to describe it? So I went inside and got a cup of water and continued to walk. Occasionally I would sip some of the water and try to determine the taste of it, but sadly I couldn't figure it out:( So how DOES water taste? Post a comment and let me know what you think:)
