"Quercetti Skyrail Suspension"
You need a lot of space and a good dose of patience to put this together (an adult is needed) but once you're done, you have a truly amazing structure.
It takes some finessing to keep the marbles on the track, "but that's part of the fun." Not for the "it's got to work right out of the box" crowd. Marked 6 & up, but really, a grown up will be needed from beginning to end.
Age: Later School Years.
