"Discover a new energy powered toy that is environmentally safe, clean and non-toxic. It has three power supply modes: salt water chemical energy, solar energy and electricity. There are four different models to build: space car, space engineering vehicle, mechanical dog and space walker. Children can learn the theory of mechanical transmission by self-assembly, discover the mysteries of new energy, improve hands-on skills, increase logical thinking ability, and also develop interest in science and enhance environmental awareness. This is a perfect start for future scientists!"
