        Disappearing Milk

        A magician pours milk into an apparently empty glass in this video adapted from the American Society of Mechanical Engineers. When he turns the glass upside down, nothing pours out. Learn how a chemical called a super absorbent polymer is behind this common magic trick. When mixed with the super absorbent polymer, the liquid is instantly absorbed, forming a more solid substance that cannot be poured out.

        This media asset was adapted from American Society Of Mechanical Engineers' Engineering Magic.
