Definition
A pestle is a blunt, club-shaped tool used to grind or crush substances in a mortar (a bowl). It's typically made of stone, wood, or ceramic. Imagine it as a mini-hammer and the mortar as its anvil, used to break down ingredients. Think of it in the kitchen for grinding spices or in a lab for preparing samples. It's a simple yet effective tool for transforming solids into powders or pastes. πΏ
