Here I want to show our new crafts from K’Nex (during these cold weather, the children and I sat at home and played mostly with K’Nex). Our new set turned out to be a mixture of K’Nex and mini K’Nex (the kids called this set Lego-K’Nex because there are lot of Lego pieces with holes to join them to thr the mini k’nex pieces). We really liked the mini K’Nes – the parts attach to each other more easily than in a regular K’Nex, even though the crafts are not as sturdy. And it’s very interesting to connect large and small parts.

Kate, can you please tell if there are only one type of big-to-mini K’Nex connector (the green piece), or there are others?
Yes, only this piece. You can also insert a mini piece on one side of a small wheel, and add a regular-sized wheel on the other side.
Thank you for the explanation!
