This is not a stuffy science book that’s getting weighed down with such things like the scientific process or school-like topics in which to organize the projects.  This is just science for the fun of it.  All the projects use simple-straightforward materials easily found.  The directions are easy-to-follow and not terribly time-consuming.  There are “icky explanations” offered for each project that explain the underlying science or broader applications.  But mostly they just look fun.  Entertainment for the scientifically minded.
