Have you ever heard of viscoelasticity?
Sloth B
Yeah, I think it has to do with materials that can stretch and return to their shape.
Sloth A
Exactly! It's fascinating how some substances behave like that under stress.
Sloth B
I know, right? It's amazing what science can discover about everyday materials.

Root Explanation

Viscoelasticity is formed from "visco-" (from Latin "viscus", meaning viscous or sticky) and "elasticity" (from Greek "elastikos", meaning able to return to its original shape). The term describes a material's property that exhibits both viscous and elastic characteristics when deformed.

Memory Tip

Think of a material that is both 'sticky' ('visco-') and 'able to return to shape' ('elasticity') — that's what viscoelasticity means.
