Any ideas for rail supports welcome. It's okay, parents are allowed
to help!

Weld the wire supports- or buy copper and solder them.

The solid copper wire for ground rods would be easy to shape and easy to
solder. If you want some great creative ideas, take a look at some
pinball machines... if you can find them. Most of them have rails the
ball rides on. They often change up from 2 rails to 4 rails and back
again depending on the twists and turns. Here are some examples.

Yeah, should have used copper. Really the only way to do this with wire
tracks is either welding steel, or soldering copper, with U supports
between the tracks so the marble doesn't have any bumps. On the
straightaways it's no problem, but turns are very difficult without a
solid support between the rails.
