My mom gave me some of that nice smelling Bath and Body Works liquid hand soap.  I got it out when I ran out of soap in my bathroom.  It was one of those nice tall bottles.  About two weeks after putting the full bottle by the sink I went in and there was about a quarter of a bottle left.  My husband and I called in number 1 son and asked him if he knew why the soap had almost run out so quickly.  He said, "I used ten pumps of it the other day because I accidently touched cat poop."  I'm not sure how he came to touch the cat poop.  Another day he picked something up by the door and asked what it was.  It turned out to be a dead bat that the cat had left as a gift.  I said, "Wash your hands immediately."  I heard him washing in there with the door shut and I think that is what really started the ten pump hand washings.  Really I am happy that he washed after touching what he touched.  I explained that it wasn't really necessary to use quite that much soap. Today I found an easy recipe for liquid hand soap, using the hotel sized soaps, on the internet.  I tried it out and it worked pretty well.  Some of the hotel soaps are getting pretty nice and I happened to have a Bath and Body Works one from a hotel.  You grate one bar of soap and put it in a glass mixing bowl with 3 cups of water and microwave it for 3 minutes.  Let it cool.  Mine congealed so I whipped it back into more liquid form with a fork.  Then I took a funnel and poured it in.  It was kind of thick and goopy and it didn't go through right away so I pushed on it with a spoon and got it to go in.  I was pretty pleased with my recoup on the wasted soap.
