About Stemclas: Stemclas was founded by a group of PhDs in various science fields. From our research career, we realized that science, technology, engineering and mathematics (STEM) are not boring. In fact, they are beautiful, colorful and joyful. The beauty of STEM shouldn’t stay only within the laboratory. Instead, they should be displayed to the public especially our kids. From then, we decided that it is our mission to make this happen. Our strategy is to let our children learn STEM when playing. These unique educational toys combine science, creativity and joy together, which promote our children's development at STEM fields. This Stemclas plasma ball will give you strong visual impact. It is suitable for all curious people. What are you waiting for? Come on, and enjoy the beautiful plasma light.
