Featuring sound-activated mode and dual power options (USB-C or batteries), it offers a captivating electric light show that can be displayed on a tabletop or wall-mounted, making it an engaging educational device for curious minds. ## 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 | |---------------|-------| | Age Range Description | Kid | | Asin | B09QH6X95X | | Best Sellers Rank | #34,145 in Toys & Games (See Top 100 in Toys & Games) #319 in Educational Science Kits | | Brand Name | Thames & Kosmos | | Customer Reviews | 4.4 4.4 out of 5 stars (271) 4.4 out of 5 stars | | Educational Objective | STEM | | Global Trade Identification Number | 00814743016989 | | Included Components | 5-inch plasma ball, USB-C cable | | Item Dimensions | 5.7 x 5.7 x 9.7 inches | | Item Type Name | STEM Experiment Kit | | Item Weight | 0.2 kg | | Manufacturer | Thames & Kosmos | | Manufacturer Maximum Age Months | 480 | | Manufacturer Minimum Age Months | 168 | | Manufacturer Part Number | 678001 | | Material Type | Plastic | | Model Number | 678001 | | Number Of Items | 1 | | Set Name | The Plasma Ball Essential STEM Tool | | Size | Small | | Theme | Music | | Unit Count | 1 Count | | Upc | 814743016989 | ## 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) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Addition! *by on Reviewed in the United States March 8, 2026* I enjoy having this thing around & mounted it on the wall near my computer. ### ⭐⭐⭐⭐⭐ Love the Placement Options - Wall or Table *by on Reviewed in the United States March 11, 2023* 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. ### ⭐⭐⭐⭐⭐ Educational and cool room decor *by on Reviewed in the United States January 14, 2026* 10 year old loves it. Reminds him of the Upside Down in Stranger Things. Sound mode works well, reacts to voice/music. ## 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.pl/products/471305843-the-plasma-ball-essential-stem-tool-classic-scientific-device-fresh](https://www.desertcart.pl/products/471305843-the-plasma-ball-essential-stem-tool-classic-scientific-device-fresh) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-08-16*
