天軌競速

My kids raced marbles down the two parallel tracks for almost an hour without fighting over whose turn it was, which never happens. The tracks are longer than they look once fully assembled, so the races actually have some suspense. Only gripe is that setup took me about an hour, but it's been worth

The suspension wires make the whole setup feel sturdy once it's built, and my kids raced marbles down the two tracks for almost an hour without it wobbling. Getting the wires tensioned evenly took a bit of patience, but the races themselves were worth it.

The two parallel tracks on suspension wires make the marbles genuinely race side by side instead of one just trailing behind. Setup took me a bit longer than I expected, but once it was up the whole family kept taking turns.
