Hi. I'm Sean Tvelia, and we're here at Suffolk County Community College today to talk about a simple experiment using ice, string and salt. What we're going to be able to do is pick up a piece of ice without using anything other than this string and the salt. So to do this, what we'll first do is place the ice cube in the water and then we'll place the string on top of the ice cube and then cover it with a little bit of salt. By adding salt to the ice we're actually causing the ice to lower its freezing point. Which means a portion of the ice is going to begin to melt. As the ice begins to melt the string will fall into the ice. Then ice water will cool down the ice significantly enough to refreeze whatever water melted through the string and we'll then be able to pick up the ice using nothing but the string.
