Calvin's inventions backfire hilariously in Scientific Progress Goes "Boink"--a popular collection full of duplicator mishaps, space-time adventures, and classic Calvin and Hobbes chaos. Calvin's duplicator and wild experiments take center stage in Scientific Progress Goes "Boink", spanning September 1989 to July 1990. Multiple Calvins, time-travel escapades, and cardboard-box inventions fuel nonstop hilarity. Stupendous Man, Spaceman Spiff, and Tracer Bullet make standout appearances, while snowball wars, mutant armies, and spirited debates about science, ethics, and creativity push Calvin's imagination to its limits. Expressive black-and-white dailies and vibrant Sunday strips showcase Watterson's humor, artistry, and philosophical insight. Unique to this volume is The Yukon Song, original material created especially for the collection, adding playful charm and clever commentary. Together, these stories highlight Watterson's unmatched ability to mix slapstick, satire, and thoughtful reflection into unforgettable adventures.
