Properties of Water

dn9144-1_600.jpg This week the class was learning the properties of water, personally I didn't know one thing about the properties of water. So when we did a lab on water and how it "stuck" to the string, wax paper, and penny I noticed that the water wasn't "sticky" there had to be something more to it. When Tonya and I did the first experiment we tried so hard to get the water to "stick" to the string. I thought: "This is never going to work" until I thought that we needed to put the string vertically and pour the water so that the water will stay on the string. Once we did this the water finally stuck to  the piece on string. Now at that point I was too excited to think about why the water did this. I later found out that the water stuck to the string because water molecules are cohesive and adhesive which means they cling together to transport the water. Now that the world made sense again I was still curious. I wonder if it matters if you had multiple strings to transport water if it would make a difference in the speed the water would move. With one string the water seemed to be slow when it traveled. Would three of four pieces of string hold more water therefore increasing the speed in which it travels? Hmmmm..... ???istockphoto_1018067_clueless.jpg
