Wonder if this really works... make your own foaming hand soap, like the kind bath and body works sells. genius and cheap. Making your own foaming hand soap is so simple. All you need is an empty foaming soap dispenser, and a bottle of Liquid Dish Soap or Liquid Hand Soap ~ you can use any scent. Next, add 1 inch (or a little more if you like) of liquid dish soap to your container. Fill the remainder with water, shake and it's ready to go!
