Intelligente Knete Amethyst (Changes colour)

The intelligent putty (known as Thinking Putty in the USA) can not only be shaped, but also exhibits amazing properties depending on the force applied:

• It slowly flows when left to sit.
• It stretches endlessly like gum when pulled apart slowly.
• If you throw the putty on the floor or against a wall, it bounces back like a rubber ball.
• It can be torn abruptly, almost like paper.
• If the force is strong enough, it can even become so hard that it shatters.
• It is neither sticky nor slimy and does not stain your hands while kneading!
• It is odorless!
• It is non-toxic!

Another great advantage: Unlike other types of modeling clay, intelligent putty does not dry out, making it virtually everlasting!.
