Pathfinders：達文西投石機木製組裝套件

My 10-year-old assembled this in under two hours with just a little help lining up the pre-drilled holes, and the wooden pieces fit together snugly without any glue. It actually launches small pellets a few feet, which made learning about tension and trajectory way more fun than any textbook.

It took my son and me about an hour to assemble, and the pre-cut pieces fit together perfectly. He was thrilled to see the arm actually launch a small ball across the room.

I was surprised how smoothly the wooden pieces fit together without needing glue—my 10-year-old assembled it in about an hour. The launching mechanism really works, and we had fun testing how far different objects would fly.
