Product Principle:

This toy uses a modular hand-cranked power generation structure and micro-current boosting technology to generate high-voltage discharge. When powered on, the internal device utilizes sound effects to stimulate the microphone for sound-to-electricity conversion, and uses the magnitude of the converted current to control the water pump’s output and thus the height of the fountain. Hand-cranking power generation, enjoying the fountain display, and listening to music provides a truly amazing experience!

Gameplay Points:

Gently rotate the generator crank handle at a steady speed while shouting loudly into the receiver located in the upper left corner. The fountain will respond by spraying water in accordance with the volume of your shouts – the louder your voice, the higher the fountain spray will reach.
