Endless fun: This Tesla music device has wireless transmission and speaker functions, capable of igniting gas tubes and creating bubble effects. The arc of the experimental wireless transmission mode can be touched freely, with only a slight touch sensation and temperature. You can use it with confidence. It is an excellent teaching tool to stimulate students' interest in science and a wonderful gift. Even if it is just placed on your desk, it is an outstanding work of art.

Long arc mode and music mode: Long arc mode releases light at a fixed frequency. When the knob is set to medium power, the light can be touched and only a slight stinging sensation is felt. Music mode: By connecting to a Bluetooth device, you can play square wave music, and the energy of the light will concentrate on the group. You can see the arc of the Tesla coil changing with the music to present an astonishingly bright melody. Compact in size but powerful in energy: Its circuit design is complex, with a larger reinforced upper magnetic ring. The optimized arc of the Tesla curved rays is long and thick, containing astonishing energy. Slowly turn the volume knob to avoid sudden violent vibrations caused by the arc sound. Before turning it on, make sure to adjust the two counterclockwise rotating to the bottommost knobs properly, so as to avoid sudden strong sounds that might scare you.

Bluetooth stability: The independently developed Bluetooth chip can be compatible with all smartphones, computers, and other Bluetooth devices, making the Bluetooth connection more stable. Type-C is also compatible. It adopts better magnetic ring technology, with a surface covered in golden transparent paint, having better dust-proof performance and higher stability.

Easy to use: The wireless transmission experimental model does not require an audio cable connection. It is easy to operate, just press the discharge button, reduce the power and frequency, and then insert it. It will present a wonderful and dazzling tone. Tesla's module can be placed horizontally or vertically, depending on personal preference. For children, this is simply a magical thing, while for adults, they will be attracted by this Tesla coil and become fascinated by it.
