===Short Explanation=== Diapers are very absorbent because of the unique polymer that they use in them. ''Polymers'' are molecules of the same type that like to connect to each other, like plastics, and they will usually stretch and bend to stay connected. Most plastic polymers don't absorb water, and instead repel it. This means that they are ''Hydrophobic'', or "water-fearing". However, the crystals that are in the diaper pad like to absorb water. These crystals are acrylic acid, and when dry they don't connect to each other. However, the crystals are ''Hydrophilic'', or "water-loving". This means that they not only absorb water, but they will try to absorb as much as 300 times their mass! As they absorb water, the crystals start to stick together, becoming a polymer gel, and even sticking to the inside of the glass as well! When we add the salt, it breaks the connections between the crystals, and destroys the polymer. Although the crystals will still hold some water in them, the salt forces them to lose a lot of it, which makes the solution liquid again.
