Manufacturer description

The Sillbird 12-in-1 Solar Building Robot Kit turns 196 snap-together parts into a hands-on introduction to renewable energy for kids ages 8-13. Your child builds one of twelve models - robots, cars, and more - following the illustrated step-by-step manual, then powers the finished build two ways: set it in direct sunlight to run on the included solar panel, or flip to battery mode to keep playing indoors after dark. That dual-power design is the teaching moment. Kids see the same machine move on sunlight and on stored power, which makes the difference between the two tangible rather than…
