Tesla Coil Bluetooth Music Speaker with Base (EU-Plug/Blue) the color is randomly sent.Features:.Ion Windmill & Wreath: The arcs heats the air to generate thrust, which ensures that the ionic winds are ejected from both ends along the direction of the arc, so that the ion windmill is able to rotate..Light Up from A Distance: Thigh quality high-voltage electric field created by the Tesla coil is capable of lighting up fluorescent lights, neon lights, retro LED bulbs, etc..Play Music via The Plasma Speaker: The audio signal affects the discharge spark of the Tesla, which vibrates the air to make sounds..Bluetooth Function: The phone can be connected to the Tesla coil via Bluetooth within about 10 meters, so that the play of the music is no longer bound by the audio cable, thus ensuring that the phone will not be interfered by the coil.The high-frequency electric field generated by the Tesla coil will cause some interference to certain electronic devices, please stay away from the coil for more than 30cm when using the devices. In addition, the discharge spark at the top of the coil is high-temperature plasma that won’t make you get electrocuted, but will ignite objects. Be careful to stay away from combustible objects when using the coil.Specifications:.Material: PCB Board + Components + Acrylic.Color: Blue.Product Dimensions: 8.5 x 8.5 x 17.5cm.Product Weight: 700g.Package Dimensions: 20 x 15 x 10cm.Package Weight: 1000g.Packing: Box
