Gauss Rifle

I have tried to build this using Geomag magnets and balls. Track is also necessary, so I have borrowed wooden track of my children.

It seems that Geomag is not very good for construction of Gauss rifle, one problem can be with different size of balls and rods . If the size would be the same it would probably work better.

I have used just two rods, 7 balls, wooden track, piece of paper between rod and wooden track (to put middle of the rod into the same height as middle of the ball in the track) and sticky tape to attach paper and rods to the wooden track.
