I built with my sisters k-nex yesterday. Grace decided to join me too. I asked Gloria if I could play with her k-nex and she said yes. Grace built a robot thing with rolling wheels and spinning arms. I find one feature super cool and it’s how Grace’s robot has wrists. Mine moves slow because it uses the rocking horse style of moving. It also has spinning arms but no wrists. I also built a bow and arrow along with a stabbing thing.
