An electric light show at your fingertips. The Smithsonian Plasma Ball crackles with dancing filaments of light that follow your touch across the glass — a mesmerizing display of atoms colliding and energizing electrons in real time.

Watch colliding atoms release energy as glowing light waves, and see the orb respond to sound and music with a pulse all its own. Packaged with Smithsonian STEM content that explains the science behind the spectacle, it's part physics lesson, part hypnotic night-light, and an unforgettable gift.
