Plasma Reaction Glass Tube — Sealed Rare Gas Science Demonstration Set

NIKOLATOY Plasma Reaction Glass Tube — Sealed Rare Gas Science Demonstration Set

Why do different gases emit different colors of light?
Atoms or molecules at high energy levels move their electrons on the orbit closest to the nucleus. When excited by an external high-voltage AC power source, electrons absorb energy and jump to higher orbitals. As they return to stable low-energy orbitals, they emit photons that form visible colored light observable by the naked eye.

Powered via AC adapter (included) — no internal battery, no USB charging required. The base uses high-voltage alternating current to excite the sealed rare gases, producing vivid plasma glow effects.

The product includes:

• One base unit (AC-powered)
• Five sealed rare gas tubes: Helium, Neon, Argon, Krypton, Xenon
