Here is a piece of nonsense trivia, if you are into gardening! (There is a link LOL!)

Those crystals in the disposable nappies work the same as the water saving crystals that you put into soil that cannot retail water (where the water doesn't penetrate into the ground, but rolls off the top) If you pull apart a disposable nappie and dig the cystals into the ground, you will get the same results. Obv I wouldn't do it with a pooey one LOL!
