Answer 2

Put some ice into a cup, then fill the cup up to the brim with water, then ask the question, when the ice melts, will the cup over flow with water. The answer is no, due to the molecular structure of ice (being hollow) which allows it to float in water. It's short, but gets the brain thinking.

Answer 3

Pour watter in a cup, place gently a pin on the water surface, it should float because of superficial tension, then add cloth softener and the superficial tension will diminish and the pin will go to the bottom of the cup
