Skyrail

My kids spent a whole rainy Saturday building suspension tracks across the living room, and the marbles actually stay on through the curves. The clips hold tight to the furniture without leaving marks, which I was worried about.

The five metre length is no joke, we ran it across the whole living room and the marbles take a good few seconds to reach the end. Setup took me a while to figure out, but once it clicked the kids were hooked for the entire afternoon.

My kids rebuilt the track into a totally different shape every single day this week, and it never once fell apart mid-run. Getting the full five metres strung across the living room took some fiddling, but the marbles keep their speed the whole way down.
