It features sound-activated mode for music-responsive plasma arcs and offers dual power options via USB-C or AAA batteries. Designed for both tabletop display and wall mounting, it’s a captivating educational tool that brings the science of plasma and energy to life. ## 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. ## Features - Learn about electricity, matter, and energy with this timeless scientific instrument in a reimagined new design. - The plasma ball sends a high-voltage, alternating current from its core, illuminating a noble gas inside the sphere and creating a mesmerizing electric light show! - Sound-activated mode enables the plasma to dance to the beat of your favorite music! - Can be powered by (4) AAA batteries (not included) or by the included USB-C cable. - Unique design allows the plasma ball to be displayed on a tabletop or hung on a wall! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09QH6X95X | | Age Range Description | Kid | | Battery Description | AAA (4) or USB power | | Best Sellers Rank | #94,986 in Toys & Games ( See Top 100 in Toys & Games ) #820 in Educational Science Kits | | Brand Name | Thames & Kosmos | | Customer Reviews | 4.4 4.4 out of 5 stars (270) | | Educational Objective | STEM | | Global Trade Identification Number | 00814743016989 | | Included Components | 5-inch plasma ball, USB-C cable | | Is Assembly Required | Yes | | Item Dimensions | 5.7 x 5.7 x 9.7 inches | | Item Type Name | STEM Experiment Kit | | Item Weight | 0.2 Kilograms | | Manufacturer | Thames & Kosmos | | Manufacturer Maximum Age (MONTHS) | 480.0 | | Manufacturer Minimum Age (MONTHS) | 168.0 | | Manufacturer Part Number | 678001 | | Material Type | Plastic | | Model Number | 678001 | | Size | Small | | Theme | Music | | UPC | 814743016989 | | Unit Count | 1.0 Count | ## Images ![The Plasma Ball Essential STEM Tool | Classic Scientific Device, Fresh 5-inch Glass Sphere, Interactive Electric Light Show | Explore Electricity, Matter, Energy, Small - Image 1](https://m.media-amazon.com/images/I/81RyX1waneL.jpg) ## Frequently Bought Together - Thames & Kosmos The Plasma Ball Essential STEM Tool | Classic Scientific Device, Fresh 5-inch Glass Sphere, Interactive Electric Light Show | Explore Electricity, Matter, Energy, Small - Thames & Kosmos Ultra Bionic Blaster STEM Experiment Kit | Construct a Robotic Foam Dart Blasting Glove | Challenging Build, Learn About Mechanical Technology & Engineering --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.dk/products/471305843-the-plasma-ball-essential-stem-tool-classic-scientific-device-fresh](https://www.desertcart.dk/products/471305843-the-plasma-ball-essential-stem-tool-classic-scientific-device-fresh) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-07-18*
