Heating the water allows it to hold much more borax in solution than it could at room temperature. So after the water cooled‚ the ability of the solution to hold the solute inside decreases‚this causes the excess borax in the solution to precipitate in crystal form on the string.When the water at a high temperature‚ water molecules have more kinetic
