Compact voltage plasma display with wireless audio and ion wind demonstration. Designed for tabletop use, this unit combines visible voltage discharge, remote lighting of lamps, a rotating ion windmill demonstration, and a plasma speaker function that responds to audio input. Key benefits Visual and interactive demonstration of voltage phenomena for education and display. The arcs generate a strong electric field that can light fluorescent, neon, and retro LED bulbs at a distance, providing clear, immediate results. Wireless audio and hands operation. The plasma speaker modulates the discharge with an audio signal, producing sound without a direct cable to the phone. Connection works up to about 10 meters, so the source can remain separate from the device during demonstrations or presentations. Tangible demonstration of ionic wind. The arc heats air to create thrust and eject ionic wind from both ends of the arc direction, causing the included ion windmill and wreath to rotate and clearly show airflow produced by the discharge. Features and performance voltage Tesla coil style discharge creates an electric field capable of lighting compatible lamps from a distance. Plasma speaker function uses audio modulation of the discharge to vibrate air and produce audible sound. Phone connection range is about 10 meters. Ion windmill and wreath respond to ionic wind produced by the arc, demonstrating directional thrust and airflow. Compact footprint measuring 8.5 x 8.5 x 17.5 cm, suitable for desktop, classroom desk, or small demonstration tables. Color and plug type: EUplug Blue 2. Applications Classroom and laboratory demonstration of electric fields, plasma, and ionic wind for physics and engineering lessons. Desktop conversation piece for hobbyists and makers who want a visual, audible demonstration of voltage behavior. Small events or photo and video shoots where visually striking lighting and synced audio effects are desired. Compatibility and notes Lights up fluorescent lights, neon tubes, and many retro style LED bulbs that respond to electric field excitation. Phone audio connection range is approximately 10 meters; for results place the phone within that distance while keeping it physically separate from the device. Compact size and EU plug make this unit ready for use in compatible power environments.
