There’s nothing quite as satisfying as solving a puzzle - that’s why this clever DIY marble-moving machine puzzle is such a fan favorite! Each wooden piece is laser-cut for precision, and paired with detailed instructions - it’s challenging enough to enjoy building for a few hours, but not frustrating, just fun! The real moving parts of the finished puzzle model send the included metal marbles along the tracks: depending on the puzzle model selected, they may move up or down, sideways, or even glide along a roller-coaster like track. Not only is building this machine puzzle model kit enjoyable for adults, it’s also a unique way to convey scientific lessons like physics, engineering, and more to children ages 8 and up.
238 precision-cut wooden pieces fit together easily; each is marked with a code that corresponds to the instructions for hassle-free assembly.
Suitable for ages 8 and up, this wooden mechanical puzzle takes approximately 4 hours to complete.
Finished puzzles measure approximately 10” wide, 9” deep, and between 6.5” and 8” tall, depending on the model selected.
