As a classic science game, the plasma planet with its touch and sound-controlled flashes is a must for all science fans. The reddish-purple flashes of light create a unique atmosphere. A light touch on the transparent 12 cm sphere is enough to concentrate the flashes on a single point or make them travel across the surface. Particularly ingenious with Kosmos: the plasma planet has a sound sensor! This means that the lightning bolts also react to sounds and even twitch to the beat of music. Physics you can touch: The enclosed instructions clearly explain the scientific background of the plasma sphere in terms of electricity and noble gases. No teen's room should be without this experiment kit. A cool gift for all science fans aged 14 and over. A must-have for every teen's room and the classic science toy: The fascinating plasma planet makes lightning flash and gives every room a unique atmosphere. A particularly ingenious feature of the Kosmos device is that the lightning can not only be focussed by touching the inside of the sphere, but can also be controlled using the built-in sound sensor. The lights not only react to loud noises, but even twitch to the beat of music! The instructions explain the background to electricity and noble gases in a simple and understandable way, and operation via USB-C cable ensures endless fun. This experiment kit is physics to marvel at.
