I just signed up to be part of the penny experiment (www.pennyexperiment.com) Jeffrey Strain is attempting to turn a penny that he found on the ground into 1 million meals for food banks. Go to the web site and you can find out all the details. You can also email Jeffrey at savingadvice@gmail.com.
Just a few details, Jeffrey gives you a number ( I picked mine and its 14) and you create a piece of art about 3×5 using your number and a penny. There will be 100 pieces of art which he will catalog and sell. But I suggest that you go to the site and read it for yourself.
