But as water gets colder, its molecules begin to lose energy and slow down. When this occurs, water molecules link together to form a crystalline structure, or, ice.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">When salt dissolves in water it separates into ions of sodium and chlorine. These ions prevent the water molecules from linking up. Even though the water is cold enough to freeze, it remains in liquid form.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The process of salt dissolving in water creates a reaction that takes heat energy away from the surrounding area, which cools it dramatically. The film of water that is slightly further away \u2014 and less impacted by the salt \u2014 then freezes, trapping the string to the ice cube.<\/span><\/p>\n<h3><b>Having Fun?<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">We want to see!
