The metal balls slide down through 4 loops one after the other until the elevator lift, which transports them back to the very top of the track. The line of the track is made of fluorescent plastic, i.e. it glows in the dark. Laying difficulty: intermediate. Estimated assembly time: 7 - 8 hours. Weight: 2kg. Designed for people over 15 years of age. How does it work? The entire structure is made of metal, plastic and fishing line.
