Foaming Hand Soap

So my family loves to use the foaming hand soap in the bathrooms.  But I am having a hard time finding the refills for it any more.
Now I can make my own.
You will need a old foaming hand soap dispenser.  Buy a bottle of regular hand soap.  Any kind.  I like to get them at the dollar store.
Fill your foaming hand soap dispenser up to a inch high with the regular hand soap.  Add water to fill up the rest of the bottle.  Put the lid back on and shake.  WALAA.  Foaming hand soap.
You will save a lot of money also because you can fill up your foaming hand soap dispenser several times from one bottle of regular liquid soap.
