The quick shiny quarter jumped over the lemonade stand.
Well, not really.
My eldest daughter, EMG found this quarter (yes, that's her hand) in her lemonade stand change.
And sold it to me for 75 cents. I think my kids are beginning to understand that when supply is low and demand is high, the price can go high, too.
Gives me an idea: why not change the price of the lemonade to be some function of the temperature? Assuming that the temperature of the lemonade stays the same, why not increase the price as the outdoor temperature increases? Why stop there? Why not factor in the relative humidity and sunlight intensity?
Hmm, I'll need to see if someone has already worked that out; otherwise, this might make a great homeschool math project for the summer.
(6/13/2010) Note: I'm working on two more tracking mechanisms (in addition to the map). One is a histogram of sorts tracking the time between finds. Another is a virtual quarter roll that shows how close we are to goal. (Hmm, that gives me an idea: what about a time-lapse slideshow of the roll getting filled?)
