Ice Cube Lifting Challenge
Young magicians will be the envy of any audience when they perform this fun Ice Cube Lifting challenge. It is always fun to challenge others to do the perceived impossible and then to magically perform the masterful feat. The salt lowers the melting point of the ice, and causes it to melt ever so slightly. The string sits in the water on top of the ice, and gets frozen to it, as the ice refreezes.
Our family was able to get this experiment to work one time but the ice cube quickly dropped from the string before we could get the picture. Other times, the ice cube stuck a little and the string eventually pulled away. The concept definitely works from a science perspective but it took some trial and error.
