Winning Science Project
The "Audio Arc" produces loud and clear sounds through an electrical arc.
Unit includes arc intensity and volume control and operates from 115 VAC wall power (a 220V stepdown transformer is required for international use). Arc is not electrically dangerous but can cause burns if contacted. It is an excellent project for the more advanced experimenter who desires to build and demonstrate an amazing and winning science project.
Simply connect to the headphone/output jack of any small radio and the sound will be created by the electrical arc in the special included acoustical chamber. There is no conventional speaker involved; the sound is created by the oscillating electric spark, which in turn vibrates the surrounding air to create sound. It’s a truly magical experience to see and hear music (or any sound you put through this device) created by pure electricity.
This project will fascinate those who just do not believe that the electrical arc is actually producing this clear and crisp tone, and frustrate them as they try to explain where it’s coming from!
