Virtually all of the topics treated are a hoot to read, though this sometimes owes more to the comedic skill of the writers than the to the nature of each subject itself.
Case in point: Because of the tall coconut tree in our backyard in Kahuku, Hawaii, the first topic I read was the study of the physics of falling coconuts, finding it humorously presented while still of serious importance. Most people, not living near coconut trees, and even some natives in the tropics, seem not to take falling coconuts seriously, but one fell from our tree, rolled down one of the long leaves, carrying it far enough from the tree to leave an 8" diameter hole in the roof of a sturdy gazebo, which could just as easily have been our neighbor's shed (or head).
To me, one of the more interesting accounts was of Dr. Cecil Jacobsen, a noted fertility researcher with whom I attended church for years in northern Virginia, who had decided to use his own sperm to impregnate many dozens of women, while telling them the semen was from other anonymous donors. The IgNobel Prize given to Dr. Jacobsen may not have seemed humorous to Cecil or his unwitting sperm recipients.
You'll find a treasure trove of wacky and fascinating matters wittily presented in this collection, and you'll probably find yourself reading it aloud to your friends and watching them crack up (or maybe just watching their jaws drop). Some of the material is appropriate for all ages. (My 10-year-old grandson loved the study of Nosepicking Among Adolescents.)
