I see that the team 1 magnet zapper has you place a steel cylinder in the can before zapping the magnets...What is the signifigance of the steel slug?? just curious..

It isolates the two magnets from each other so they actually get zapped(this is a not so techincal way of describing)....if you don't put the slug in there, the zapping process doesn't work very well....
