As long as the excavator USES the hydraulic system to control the swing arm to complete the excavation work, now we understand the transmission principle of the hydraulic system through experiments. Features: Cultivating children's interest in learning and desire for knowledge can help improve their academic performance. Scientific knowledge in small production can lay a foundation for future inventions, mathematical and physical learning. Improve children's sense of innovation and ability, let children win in the starting line, on the social more competitive. Nowadays, children generally lack practical ability and strengthen the cultivation of practical ability, so that knowledge is no longer an issue. Material: High quality plastic parts, specially designed for scientific experiments, multi-functional, expandable, material safety and environmental protection odor-free. High quality natural wood is used as the main structural material of the model.Environmental protection, close to nature, safe and non-toxic, children can freely paint color creation. Using quality electronic components and accessories, stable performance, safety and reliability. Note: Liquid in the syringe is not included and needs to be filled by itself
