The first two come from the Taste of Home Cooking School--
1) If you need to cut up apples ahead of time but don't want them to brown, put them in a bowl of 7-up until you are ready. She did say 7-up worked specifically. Other lemon-lime sodes didn't work as well.
2) When cutting up fresh herbs (basil, cilantro etc.) it is easier to put them in a small bowl, then use kitchen shears to cut them up. Much easier than a knife and cutting board.
And this one I read a couple of times recently and had to try.
For softer hair, add a couple of scoops of Baking Soda to your shampoo when you are washing your hair. I tried it yesterday and my hair was softer.
