This neon green and grape roller coaster is impressive in both size and scope. When fully built the coaster stretches 6 feet long and stands 3 feet high. The directions are detailed and clear, and we had no trouble putting it together. It did take us a bit over five hours, though, and it's likely that any child under 12 will need parental assistance. But assembling it is half the fun. When finished, the track careens so hazardously, it's hard to believe the cars will stay on, but they do! The plastic chain hauls the three cars up slowly, just like a real roller coaster, and the sound effects box re-creates the noise so perfectly you'll squirm with anticipation. After reaching the top and passing through the serpent's mouth, the cars begin their dizzying descent past the sound effects box, which has now switched to emitting enthusiastic and terrified screaming. Gravity and centrifugal force whip the little cars along the rest of the track until at last it reaches the beginning of the ride, only to be towed up for another round. If you don't have 6 feet of space, there are instructions for a smaller version, and you can turn the sound effects off if you prefer to play quietly. Entirely worth the time and effort, this is ideal as a family endeavor. --M. Sullivan
