As a review for newton's laws, my teacher has assigned my class to do an egg drop test. does anyone have any tips on what to use? so far, my group has sponges, marshmallows, air in a bag. also for the parachute, would cellophane or plastic work better?

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
