Hi Jazz,
We do something similar, although not from the 'Thinking science" program. We use flexible plastic tubing from Bunnings, about 30mm or so in diameter with glass marbles- have used ball bearings as well. We have also used the clip together conduit- sorry I don't know the proper name- but it has a rectangular profile and is about 15mm wide- one half of this makes a pretty good track for a small marble or ball bearing.
Good luck with your sourcing!
Jodie
