You discovered: HEAVY & LIGHT!

You weren't just riding a seesaw — you were a WEIGHT detective! The friend sitting DOWN LOW is heavier, the one UP HIGH is lighter, and when the seesaw sits perfectly straight, both sides weigh the SAME! You even found the heaviest friend of all by watching who kept winning. Fruit scales at the market 🍎, playground seesaws, even grown-up scales — they all tip and tell, just like yours!
