How much would you pay for a toy which is innovative and promotes healthy eating?

Currently working on some market research for an innovative educational toy which will revolutionise how children think about food and healthy eating. It will create an increased nutritional awareness through positive association with the good foods using multi sensory technology. Wondering how much would parents pay for a product aimed at 3-5 year olds?|||$12 to 20 I would say not seeing the product.
