I don't have children so I don't have any diapers laying around my house, but I know they are expensive (I recently picked up a pack for my future niece)! I always thought they only had one purpose but now I've found out you can use them for something else!

I haven't tried this yet, but it makes sense. You have to take the cotton filler out of the diaper and mix it with the soil and the ingredients in the diaper help the soil retain moisture longer. It makes sense if you think about it, a diaper can hold a LOT of liquid but the funniest part of this video to me was the sidenote by the "King of Random." He says in the video that you can use slightly used diapers for this. I don't know about you, but I know I wouldn't want to do that! lol
