How to make a simple railgun to demonstrate the principle to children?

Using only some batteries (maybe a car battery, but certainly nothing larger than that) and readily-available materials, how can I design a classroom-grade 'railgun' that demonstrates the basic principle
It would seem to be quite simple, but a couple of minor attempts I made produced no results. I have very little experience with electricity outside of basic safety protocols and some electrolysis experiments.
There was a recent article
in the news about railguns my nephew brought up and I thought a simple demo might help get him excited about his science classes.
