I am a primary school teacher and consider this product to be one of the better things I have purchased for my class. It has provoked much discussion and had my students think about how and why it works. Some have even used their own time to find out more information and applications for gyroscopes in the real world. Being able to view diagrams is one thing but to actually experience it in hand is another. AWESOME product
