Aaron's Thinking Putty World Mini Glow in the Dark - Krypton

Krypton is a noble gas that prefers to stand on its own and rarely plays with others. When stimulated with electricity, Krypton glows brightly and reliably. From light sabers to kryptonite, Krypton’s unique green spectra have inspired many pop culture and sci-fi favourites. Krypton is white and glows its signature green in the dark. Charge with sunlight or a Blacklight Keychain for fantastic brightness! Tin is 5 cm (2 inches) in diameter. 3+ years.
