## Overview

The Thames & Kosmos Plasma Ball is a 5-inch glass sphere that creates a stunning electric light show by sending high-voltage alternating current through noble gas. It features sound-activated mode, dual power options (USB-C or 4 AAA batteries), and versatile display setups (tabletop or wall-mounted), making it a stylish and educational STEM tool perfect for exploring electricity, matter, and energy.

## 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: Great Addition! - I enjoy having this thing around & mounted it on the wall near my computer.
Review: Love the Placement Options - Wall or Table - This was a Christmas gift for a budding mad scientist because a "working Tesla coil" was right out. The ball works perfectly, and was the envy of everyone on Christmas morning. Especially great is the option to mount it on the wall and rotate it to one's liking, or place it on a dresser or desk. This is the 3rd Thames & Kosmos Plasma Ball I have gifted to young science enthusiasts, or to kids who just love to play with interactive lights. After buying some other brands that turned out to be "baby toys" (or just plain junk) Thames & Kosmos is the ONLY BRAND I will purchase - the QUALITY is UNBEATABLE and the price is really reasonable for the options it provides.

### ⭐⭐⭐⭐ It works
*by K***Y on March 20, 2025*

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.
