For Christmas, I got my nephew a Snap Circuit Jr. It is a pretty cool toy that lets the little one conduct electricity based experiments. It is recommended by The National Parenting Center-Seal of Approval, Dr. Toy 100 Best Children's Products and Dr. Toy Best Educational Products. Really amazing toy for only $25. The thing about this toy is that each piece is labeled and each piece is equally important than the other piece. Translation: You can't lose a piece. Initially, we put the little pieces in a bin, but that didn't work since it meant picking out each piece manually to see the label and it was a bit much of work.
