HAL - Hyper Academic Laboratory
Summary and Preview
One day, on her route to school, Rika notices a strange laboratory on top of a building. When she goes to investigate, she discovers the bizarre Hyper Academic Laboratory, where the childlike, microscope-goggled Kijirushi conducts his research along with his mysterious, shadow-like homunculus. Rika finds herself dragged along through explanations and demonstrations of various scientific mysteries, such as sea monkeys, the Schrodinger's cat thought experiment, the doppler effect, and much more!
An educational manga for adults by the author of the popular "Lucu Lucu" and "Wahhaman," delving into the mysteries of modern science and other curiosities. Incidentally, though some of the concepts explained are real and factual, the author occasionally engages in amusing fabrication.
