The Blow Light is a wind-powered toy which teaches kids about wind energy. The toy has one green and two blue LED lights which are powered by blowing on the 2.4 inch rotor blade. Though the practical uses are limited, there's no doubt a product like this would appeal to a great deal of people.

Businesses that create educational toys and games cater to a market for parents and teachers that want to make learning fun for their kids. Often times, kids learn more when they are playing and using hands-on items rather than at a desk listening.
