🍋 Pascal's Law in Action: The Lemon Squeezer
📖 Story: Grandma’s Magic Lemon Squeezer
One sunny afternoon, Riya watched her grandma squeeze lemons to make refreshing lemonade. But instead of using her hands, Grandma used a **handheld lemon squeezer**. She placed half a lemon in it and pressed the handles together. Juice gushed out easily from the tiny holes below.
“Why does it come out so fast?” asked Riya.
Grandma smiled, “That’s Pascal’s Law working its magic! When I apply pressure on the large handles, that pressure travels evenly through the squeezer and acts on the small lemon area to squeeze it completely.”
Riya was amazed — a simple kitchen tool using a science law!
🔬 Concept: Pascal’s Law
- Pascal’s Law: When pressure is applied to a confined fluid, it is transmitted equally in all directions.
- Hydraulic Machines (like car jacks, brakes, presses, lemon squeezer) use this law.
- Small effort on a large area creates a large force on a small area.
- Useful in lifting, pressing, squeezing with less effort.
