How does Newton's third law relate to an egg drop?

Newton's third law, which states that every action has an equal and opposite reaction, can be related to an egg drop because the forces pushing the egg up and down must follow the law.

states that for each action, there is an equal and opposite reaction.

An egg by itself will splat against the concrete if dropped from a height. The point of an egg drop is to keep this from happening. In other words, you must make sure that the downward force of gravity has an opposite force, great enough to slow the egg down enough to make sure it doesn't break.

If you tie a parachute to save the egg, air drag pushes the parachute up, but the force of gravity on the egg pushes it down still. However, the air drag works opposite gravity and slows the egg's descent enough to ensure it doesn't break on impact.
