I've been intriqued by this water of ZamZam.

According to a German scientist who has studied the water, he reported that the water is several times heavier and more energetic field than normal water. It betters your energetic field and make you better.
He used samples of the water, which was sent to European laboratories for testing. And he said the energy was still so powerful, despite the distance taken from the source, so how much energy at the source!

Hear it from the horse's mouth German scientist

For those who have not heard about this, let me bring you up to speed...
Do you remeber the story of Hajar or Haggar the 2nd wife of Ibrahim (May God be pleased with them)? Centuries ago, after Hajar gave birth to Ismail, Sarah began to feel jealous. Sarah asked Ibrahem to send Hajar and the son away from her. God revealed to Ibrahim that he should take Hajar and the infant Ismail and take them to Makkah. So he took them and left Hajar and her child Ismail in an isolated place in which there was no water. He left them and went back to Palestine. Conversation:

Hajar said to him, "For whom are you leaving us in this forsaken valley?"
But Ibrahim went and left her, and she said, "Has God commanded you to do this?"
He said, "Yes."
She said, "Then God will not cause us to be lost."

Hajar searched desperately for water in the hills of Safa and Marwa to give it to her young son, Ismail (pbuh). As she ran from one place to another in search of water, her child rubbed his feet against the sand as he cried. A pool of water surfaced, and by the grace of God, which came to be called Zamzam water.

Ever since it came into existence at that time of Ibrahim (pbuh), many, many centuries ago, this is a well that has never dried up. Actually, it has always remained filled up and met the demand of the people.
It has maintained its chemical composition and taste since the time it was analyzed. Pilgrims have always carried it and as they go back home, all over the world after visit to the Kabah every year during Hajj.
No one has ever but have never make a complaint about the water. They have enjoyed its refreshing effect.

ZamZam water has never been treated chemically or chlorinated to purify it. ZamZam water has no biological growth and no vegetation that is mostly observed in other wells.

On that note...Check out Dr. Masaru Emoto's work http://www.highexistence.com/water-experiment/

Some of this scientific claims are damn interesting/questionable.

This is just like the loliondo drink by babu

Water is not the same. Scientists have tested water and concluded that there is a difference between artificially pure and naturally pure water. Even the purified water you drink sometimes maybe "dead" and has no energy in it.

There is so much scientific facts about water than we know.
