Kavi and the See-Saw Scale ⚖️

Kavi put an apple 🍎 on one side of a balance and a feather 🪶 on the other. The apple's side sank down and the feather's side went up! "The side that goes down holds the heavier thing," said Kavi. Then Kavi tried a big fluffy pillow and a small book — and the book's side sank! "So big does not always mean heavy. The balance tells the truth."
