I wish I had a dollar for all the pennies I flattened for the little ones. Never derailed but we did warn them to stay away, never know if you caught one just right it might fly like a tiddly wink .

They can sure fly with some force if caught just right. I used to have a friend in Jasper Texas who could hold a penny between two fingers and with a snap of his fingers make it fly with enough force to put a ding in a car door. No kidding. I watched him do it several times.
