This website is unique and innovative.
All in All, I loved this website. They have some fun and innovate experiments which can make kids happy and excited for Science and Math. Usually, kids do not like Math or Science, but maybe because of this website they will start liking it.
How I Use It
As I have no first-hand experience with this website for teaching. But if I were to teach with this website then I would use it for Mathematics and Science. When a kid sees some Chemistry or Physics experiment, they'll be in excitement and think as if it is a magic. Which is why I would use this website for kids to experience wonderful chemistry experiments a.k.a magic shows.
