The kit includes a book with step-by-step instructions for building 10 different machines, including a pop-up flag, a spinning top, and a basketball hoop, as well as the LEGO pieces needed to build the first machine.

The chain reactions that the machines create are a lot of fun to watch and will keep kids engaged and learning.
