The Earth-Moon-Sun movement demonstration model is a simple three-ball instrument model that can vividly describe the intuitive teaching model of the relative movement between the ground,the month and the day. This model is great for educational and entertainment purposes.

Telegraph is the equipment used to send and receive telegrams. Note:The telegraph has two display modes.

Normal acousto-optic mode: sound and led work at the same time.

Silent security mode: only Led works and the horn does’t sound (mute opereation prevents the telegram from being menitored).

Newton’s pendulum is a desktop demonstration device, five spheres of the same quality are fixed by slings and arranged closely to each other. When swinging the rightmost ball and colliding with the other four closely aligned balls while swinging back only the leftmost ball will be ejected.

This elevator is a vertical lift elevator model. The control circuit controls the forward and reverse rotation of the motor,and then the elevator car is lifted by gears and ropes.

The excavator mainly uses the hydraulic system to control the swing arm to complete the excavation work. It is a excellent learning tool that can be used to introduce and reinforce the principle of hydraulic transmission.

All these parts are made of high quality, non-toxic, odorless watercolor materials great for kids to have fun.Easy to assemble and let children focus on the construction process.With detailed instructions, easy to assemble.
