Tell him the idea -- and voila!
R's oldest collected lightbulbs when we went to the Madaket Mall (a.k.a. the Nantucket transfer station) and gathered some lightbulbs hoping dad would be crafty with her. She had found this idea on the www. and was dying to make one. While the kids slept this morning, he got to work, wanting to surprise her for when she got up. The reaction? Two thumbs up.
Right now it's set into a small clear bowl to hold it upright, we're brainstorming to come up with a cool alternative made with found objects.
