Geomag - MECHANICS GRAVITY UP & DOWN CIRCUIT - 330-Piece Building Set with Magnetic Motion, Certified STEM Marble Run Construction Toy for Ages 7 and Up

Calling all future engineers. The up & down circuit set is the most complete one in the gravity range and is based on the movement of the spheres. Their weight moves a never-ending spiral and starts a real gravity motor. In this system of magnetic gears a second spiral is activated, allowing the spheres to ascend as if they were in an elevator. Once they reach the top of structure, the spheres enter a circuit full of amazing magnetic tricks and then descend once again to keep the gravity motor active. At the heart of this circuit are the 330 pieces contained in this set: 21 magnetic rods, 39 steel spheres and 270 plastic mechanical elements. Gravity is the innovative evolution of the Geomag mechanics line. Developed with expert players in mind, the new construction system is based on an innovative "gravity motor": this uses the weight of the Geomag spheres to Kickstart the mechanisms and movements of the Geomag mechanics structures. The motion is provided by the invisible forces of gravity and magnetism, without using electricity or batteries. The play experience is based on these fundamental principles of physics. Mechanics gravity is a STEM product that can truly stimulate curiosity and inspire to learn more about science.

Doc fetch goes through Layer's Aerospike pull-through cache; cache hit served the row without touching turbopuffer. The similar query asks Layer for nearest neighbors of the stored product vector — queries don't go through the doc cache, so no cache header is set.
