Today, I would like to introduce a very popular diy toy:6 In 1 Robotics Science Kits for Kids 

6 IN 1 STEM KITS: These science kits contain a reptile robot, a balance car, a bubble machine, a fiber lamp and a buzzer wire game kit. Kids will be proud of building their own robot. 
Our robotic kits designed for kids age 8-12 are cool stuff for a budding inventor, very suitable for elementary students to show their talents in a science fair. Packaged in a beautiful gift box, these assembled electronic gadgets are perfect gifts for boys and girls for birthdays and Christmas

EASY TO ASSEMBLE: All components of the kits are made with odorless and safety materials. Mini screwdriver and detailed step-by-step instruction manuals make it easier and more convenient to assemble the model.
By playing with these electric robots, children's curiosity and interest in physics will be stimulated, and they'll know how much fun it is to create a circuit by themselves
