The Combination Of Soap!

So about a month ago I went to Sam's Club and bought in bulk.  I got a good deal on some hand soap.  It was a 4 pack of the soap that turns into foam.  I prefer that stuff over anything else.  I don't know why but it just works for me.

I noticed the other day that all 4 bottles of soap were about empty so I had a brilliant plan of combining them together to make more soap.  I haven't tried it out yet though.  I'm eager to see what smell comes out of it and what color.  I guess the color wouldn't matter since it all comes out foamy.  After combining 3 of them this is what I got!  I thought it was pretty cool so I had to share.  What different things have you combined to make make more of something?
