This Lumin Disk demonstrates fascinating physical effects and one of it should therefore be in all geek rooms. After switching on the disk you can see the fascinating play of tremorous light flashes and you can even control them using the touch of your hand or sounds!
The disk uses the following principle: The disk is made of glass splinters, which are located between two glass plates. Between the glass splinters is an inert gas that can be activated through high voltage, so what you can actually see is the stream of electricity. If you now touch the plates, a part of the electricity flows through your hand and causes a different light effect on the plate (this is absolutely safe because the current is very low). If the sound mode is activated, the plate additionally registers sounds in the background and switches itself on and off according to music.
The plate has a diameter of about 15cm and needs a 230V connection (standard euro plug). There is a blue and an orange color available.
Technical info:- Dimensions: 15cm in diameter
