Smush it, squeeze it, stretch it—NeeDoh toys are everywhere! How do toy makers design something that will squish over and over again without popping?
Many NeeDohs have thick goo inside. It’s often made with a special polymer. This super-flexible plastic material can be stretched and pulled without breaking. The polymers in NeeDohs can act like a liquid or a solid.
Other squishy toys like slime are made up of polymers too!
