## Overview

The Thames & Kosmos Plasma Ball is a 5-inch glass sphere that creates a captivating electric light show by sending high-voltage alternating current through noble gas. Featuring sound-activated mode and dual power options (USB-C or AAA batteries), it serves as both an interactive STEM educational tool and stylish decor, perfect for ages 14 and up.

## Description

Marvel at the wonders of the universe with this mesmerizing electric light show. The plasma ball creates a fascinating display of glowing electric tentacles, like lightning flowing from your fingertips. Plasma is the fourth state of matter. Neither solid, liquid, or gas, it is a super-charged ionized gas found in every star. The plasma ball works by sending a high-voltage, alternating current from a Tesla coil at its core, through a noble gas, to the inner surface of the glass sphere. Escaping electrons cause the inert gas inside the sphere to light up, creating the amazing effects. You can actually see electricity in the palm of your hand with this incredible device. The plasma ball design allows you to display it on a tabletop or hang it on a wall like a sconce. It can be powered via a USB-C cable or batteries. Turn on the sound-activated mode and watch the plasma arcs dance to the beat of your favorite song.

Review: Nice item - Got this for my grandson on his birthday. He loves it.

### ⭐⭐⭐⭐ It works

It runs on battery but also comes with a plug. We haven’t tried the plug in but could be worth it as it does go through batteries. Not super bright.
