Thinking Putty
Thinking Putty is like Silly Putty with special chemical properties. One formulation changes color when it heats up (and the company can match your company colors), another formulation can be magnetized and a third glows in the dark. The putty is packaged in a tin with a custom four-color label, making it useful as trade-show giveaways or promotional gifts. It also could be given as a stress-relieving squeeze ball at a company retreat. Available in three sizes; cost per unit, $4-$6. (866) 578-2845;
