Operation Egg Drop 

Background: The Army are often called in to help people I countries in need. For example, when a country is hit by a hurricane the Army is called in to deliver food, medical and building supplies to support people who are in desperate need. Not always can the military aircraft land at the airport due to damage or the people who need the deliveries are cut off from towns and roads. The military need to be able to drop off the deliveries from a height to get to where they are needed without landing the plane. 

Your mission: The Army have contacted you to build a device that could protect an egg that when dropped from a height the egg will stay intact (Not break).
