Krypton Glow In The Dark Thinking Putty
If the usual pink putty isn't wowing you like it used to, then you need to get your hands on the next generation in malleable masses. The cool new Krypton Glow In The Dark Thinking Putty may appear innocent and milky white in the daylight, but when the lights go down, it magically begins to glow an eerie radioactive green for hours. It's translucent, so the glow appears to come from deep within and it even sparks when you tear it. No batteries or uranium needed, just charge it up by exposing it to a bright light first.
