馬達與磁鐵STEM鬆散零件套組 - 178件

My five-year-old has been obsessed with the included real motor, which even I didn't expect to work so smoothly on the first try. The 178 pieces give us just enough variety to build a spinning top one day and a magnetic maze the next.

Wish I’d found this kit sooner—it’s got 178 pieces, so the kids can split them between two projects at once without anyone fighting over parts. The magnets click together with a satisfying tug, and my son’s first spinning motor setup actually worked on the third try.

My five-year-old has been building little cars for days with the included motors, and the way the magnets click together keeps him engaged far longer than I expected. The sheer number of pieces—178—means we can both build something different at the same time.
