I have a question about the mechanical hand holding the patent.  We assembled the model according to the directions, but the "thumb" does not grab anything.  There are parts like a rubber band that make you think that the hand is supposed to move in some way, like it is able to have the fingers close down around something, but ours doesn't, unless you just physically push the fingers together.  Have we assembled this correctly?  Because the only thing you can do is just push the arm forward, but the hand does not actually grab the patent.  We would love to know what is supposed to happen.  Many thanks for your time!
