Thinking Putty Phantoms dramatically change colour when exposed to UV light.

Hold this putty outside in the sunlight and it will almost instantly change colour. Once you cover it or bring it back inside it will revert back to its original colour in about a one minute.  You can also use the included black-light keychain to write or draw a picture directly on the putty.

If changing colour under UV light isn't cool enough Phantoms also glow in the dark when the lights go out.

Thinking Putty Phantoms come in two colour choices:  Foxfire - a minty white that changes to a vibrant bluey-green when exposed to UV light and glows green in the dark. Or Arctic Flare - a snowy white that changes to a brilliant, pinky-red under UV light and glows orange in the dark.

And just like all Thinking Putty products they can bounce, stretch and rip.

I could go on writing about how great this putty is, but you have really got to see it to believe it, so we made you a video.
