Homemade Foaming Hand Soap

I love foaming hand soap. It lasts longer and doesn't leave little globs of soap in the sink. Did you know that the foaming soap is actually all about the bottle and that it is really cheap to make? Just take an empty bottle and add about a Tablespoon of dish soap or liquid hand soap. Fill the rest of the bottle with water and gently shake. Now you have foaming soap. Remember though that you have to use a bottle that was originally made for foaming soap.  

Now if I could figure out how to keep the little globs of toothpaste out of the sink.
