Every kid will be excited to put the pieces together and attach the gears creatively and independently. It is amazing to see their faces light up when they are watching their creations spin! Build your base with interlocking plates then insert axles and connect gears so that they rotate at the same time. Finally either turn the crank or turn on the motor to start a spectacular chain reaction and watch the exciting visual effects. Manufacturered by Newdeebee. The square plates interlock easily to form flat or 3D structures. You can even make a gear-car! A battery operated motor is included to enhance your creating experience. Gears would be able to rotate automatically once motor is turned on. A set of stickers is included so you could customize your gear set. This toy is recommended for children who are aged 5 and up. This toy is not suitable for children under 3 years due to small parts. Please do not place the gears close to hair to prevent being caught. This toy set provides hours of fun while introducing children to basic principles of mechanics. It is also great for bringing your families together while they try to work as a team.
