Here's the scientific skinny on color-changing Silly Putty: "Silly Putty uses thermochromic (a big word for color change through temperature change) to change color. Changeable Silly Putty is formulated with a base color, to which an additional thermochromic dye is added. When the putty is handled, body heat causes a chemical reaction that makes the thermochromic dye disappear, leaving only the base color.

Silly Putty is made primarily from silicone and color pigments. Silly Putty was discovered in 1943 by James Wright who mixed boric acid and silicone oil together. Colors are also added to Silly Putty to create a broad array of fun shades. The combination creates a "solid liquid" which can be molded, stretched and bounced. See similar questions...

You know, we're a little cloudy on that, too. Some say its because the egg shape provides the ultimate package for this unique liquid solid.

Still others say its because, well, eggs are kind of silly in their own right... See similar questions...

A man-eating flowering plant from the deepest, darkest jungles of the Amazon...only kidding. Silly Putty was discovered in 1943 by scientist James Wright, who was working on a synthetic rubber substitute for General Electric during World War II. While the mixture of silicone oil and boric acid was a dud as a rubber substitute, the substance did have some unique properties. Wright found that it could be molded, stretched and bounced.

Prominent physicists and basement experimenters have been pondering over this one for years. Several treatises have been written on the subject, highlighting the super bouncing properties of Silly Putty. How high it bounces depends on how high you drop it from, the surface you're bouncing off of, and the size and shape of your Silly Putty piece. Our scientists have done no conclusive testing on Silly Putty's bouncability. See similar questions...

Well, we can try. Maybe it's because it comes in an egg (see above) or in a bunch of cool colors. It's been around since your parents were kids, and we all had one when we were kids (many of us still do!). It's part of our collective consciousness, like the Slinky, the yo-yo, the 64 box of Crayola crayons, the Barbie doll, the GI Joe, the Matchbox and Hot Wheels cars. Most importantly, though, even after 50 years, it's still a ton of fun. See similar questions...
