Here's a quick snap of Mr. J with some of his favorite toys - Kid K'Nex. While they come with an idea book - his sets can make boats, cars, bugs, and more - my guy got more imaginative this particular day. This creation is called a "booger buster."
According to the demonstration we were given, you have to rock it back and forth. I don't know much more about how it operates - nor do I think I care to. But, Mr J was mighty proud of this particular creation, so it warranted a quick snap and a quick post by a proud, though somewhat puzzled, mama.
