Another consignment sale find: this awesome marble run. We had one before, but there were some complicated parts, and this one is much easier for Ian to build by himself.
We built this giant run together, and then Chase, by some miracle, chose not to destroy it, but to play with it. He laughed hysterically every time he sent a marble down, and I managed to catch him a couple times before the novelty wore off.
Note: you must either turn your computer screen on its side or lay down to watch this video. Sorry!
