Take two ice cubes, a thin thread strong, a bowl of water and few salt. This experiment will make you hold the ice with the thread. Place the ice cubes in the bowl of water. Now place the thread on the ice cubes so that it touches both the ice cubes. Try to lift the thread. The thread will come alone without the ice cubes. Now place the thread on the ice cubes, so that it touches both the ice cubes. Now sprinkle salt on the thread and the ice cubes. Leave it for few minutes. The salt will decrease the temperature and the make the water near the ice cube and the thread to freeze. After few minutes , try to take the thread. You could see the ice cubes also coming along with the thread. The salt reduces the temperature and hence the water freezes near the ice cubes which makes the thread and the ice freeze together. This simple experiment explains the science of water and its freezing point.
