Plasma speakers are nothing new. We have covered a couple of them that react to your touch and also dance to the beat of your music. This Plasma Ring Generator Bluetooth Speaker is the coolest yet. It is not only a fun science toy but also generates a plasma toroid ring that reacts to the beat of your music. You can put a spherical glass with low pressure gases such as Xenon or Argon on this to see different colors.
This speaker has a 3D printed body. You shouldn’t touch any of its coils but you can touch the glass safely. The knob lets you interact with the plasma ring.
