Helping Hand

Today in class, we watched a few videos of other people that did the Design Squad Helping Hand Challenge. I didn't think many of their designs worked smoothly, except the one in the last video (the one featured in this post). It's hard to see exactly how their grabber worked but it seemed to be like a "mouth" grabber. I think my grapper will work better than most of the ones in the videos we saw today because we were able to construct ours mostly out of wood.
