This robotic creature is a great example of the ways in which the tiniest things in life can bring big pleasure. While it's basic as can be, there is just something about this little bug that inspires fascination!  The Hexbug is a robot that reacts to touch and sound. When the bug senses an obstacle with its antennae, it backs up and starts off in a new direction. Turn it on, and watch it go! Then talk about how it works to jump-start an interest in electronics.
