Nice & simple. The train is just an AAA cell and neodymium magnets, propelling itself inside a copper "spring" tunnel. Looks like Dad was mightily involved with Junior's Science Fair project!

    That's a how-to and a half. Dad gets an "A", junior gets a "D" for carrying it to school in-tact.

    I liked how they clearly showed LEAD to weight the pen-front engine, but never mentioned lead, simply saying "use a non-ferrous metal". :) This train is non-stop and non-RoHS!
