Silly Putty is a goo-like toy that comes in a plastic egg. Silly Putty is manufacture by Crayola, LLC and is trademarked by them as well.
It is based on silicone polymers that have unusual attributes. It can bounce, stretch, and flow like a liquid. It was created by accident in an attempt to create a rubber substitute during World Ward II. It is also somewhat of an adhesive; if you stretch it out and press it against a newspaper, it absorb the newspaper print you pressed it on and can also transfer it to another surface. If you put it in hot or warm water, it will somewhat melt, but it can also harden, and will eventually return to its initial viscosity.
Silly Putty has some household uses as well. It can pick up dirt, lint, hair, or ink from various surfaces. Physical therapists have used it to aid hand injuries and can be used as a stress reduction tool. It has even been taken up to space to hold down tools for astronauts in zero gravity!
