The boys were in the bath the other night and Will remembered that he had made a fun discovery.  He informed us that he had (somehow) discovered that one of his Lego guys' head glowed in the dark!  He popped out of the bath, dried off as fast as he could and went in search of the glowing Lego guy.  He came back a minute later holding the head.  He turned off the light and sure enough, it was glowing brightly.  He looked mighty pleased with himself and said "I had no idea it glew!"
