The PhänoMINT series delights with phenomenal experiments in the fields of mathematics, computer science, natural sciences, and technology. The small experiments with a big "AHA!" effect particularly thrill schoolchildren whose interests lie in the STEM area. With the "PhänoMINT Spinning Top" experiment from Moses Verlag, children learn why the top keeps spinning. It includes a spinning top with a pencil tip and interesting information on this topic.
