Krypto-light putty is the most fun you can have with a non-Newtonian fluid! The Science Putty exhibits properties of a liquid and a solid all at once. Pull it hard to snap it apart or slowly see how far it can stretch.
The secret behind this glow-in-the-dark putty is the long-chain polymers that are locked together inside. Shape it, bounce it, or stretch it. This glowing putty is perfect for exercising your fingers and relieving stress.
