In a chain reaction, one thing leads to another, which leads to another, which leads to another, which. ..well, you get the idea

With the stuff in this kit and a pile of your own ordinary LEGO bricks, you can build Ten awesome machines that can be combined to make dozens of different chain reactions that use many steps to do. ..a whole lot of nothing (or maybe something vaguely useful).

Your machine could toss a gum wrapper into the trash, amuse your dog, deliver a message ('Oh Yeah!'), ring a bell, and generally make you the envy of the neighborhood.
