The Korea Science & Creativity Festival is an annual event for various experience for science and technology, ranging from future technology showcase by research centers, to science teaching aids and mini experiments by students. NIMS (National Institute for Mathematical Science) participated with other Korean government funded research centers and presented IMAGINARY. Many participants - mostly students and preschool kids - were fascinated by interactive features. We suppose that this event achieved the largest number of participants, among all NIMS-IMAGINARY events after ICM exhibition.
