Krypton is a noble gas that prefers to stand on its own and rarely plays with others. When stimulated with electricity, this natural element glows brightly and reliably.
From light sabers to kryptonite, Krypton’s unique green spectra have inspired many pop culture and sci-fi favorites, including our own Krypton Glow Thinking Putty®! White by day, this putty glows the signature green in the dark.
Crazy Aaron's putty is non-toxic, won't dry out, and won't leave a sticky or slippery residue on your fingers, so it's great for stretching, molding, and playing by kids and adults alike!
