One of Jack Cole's favorite themes was SCREWBALL inventions. He populated his stories with wacky stuff, such as Midnight's "secret vacuum gun," which fired an avenging suction cup at crime.
One of his first series, Dickie Dean, Boy Inventor, is built around such nutty devices are the "time camera" and an accordion hat retriever. Of course, Plastic Man was filled to the brim with wacky inventions, starting with Plas inventing new forms to stretch his body into.
This theme has its roots in the great screwball comics, which in turn have their roots in the American entrepreneurial spirit. For more on crazy inventions and some great SCREWBALL comics, be sure to check out my article at my MASTERS OF SCREWBALL COMICS blog...
