Mechanism of fountain

I will describe the mechanism of "Prismatic Fountain".

When you remove the fountain part, you can see the hidden mechanism.

That mechanism revolves the seven-color-clear-bricks with a motor, and illuminates from beneath.

It's a seven-color fountain, but the parts are divided into six. Well, the proportion of yellow and clear is a little bit small. (^^;

As I mounted four lights, I managed to create a sufficient amount of light.

It slowly rotates clockwise.

The MINDSTORMS is used to revolve the motor, and the battery box is used to light on/off.
