Features:
The kit can be assembled into a fast train.
It's not the kind of blank building blocks, they will move under sunlight! No batteries are required. When sunlight shines on solar panels, the small toys get sun power and move.
Teachers and parents can use the toys to teach children the benefit of solar energy, let them have great joy, nurture their imagination & creativity and allow young builders to focus on self-motivation, perseverance and manipulation.
It’s easy to assmble the parts, so children can learn by themselves and have sense of accomplishment at the same time.
The solar bullet train is an excellent beginner building kit designed to teach how solar power is used to drive a small motor.
Can work well not only in sunny days, but also in rainy days or at night by using a 50 watt halogen light to replace solar one.)
A good teacher and helpful friend for kids. (Recommended for ages 10 and older.)
