IntroductionDue to the delicate nature of the common egg,

they are rarely recognised as the safest of God’s creations. In this project we hope to

rectify this unfortunate situation for the greater good of the egg, by correcting God’s horrible

horrible mistake.

Natural protection

3. what we can do to improve the safety and comfort of said egg, via examination of various physical laws.

2. the overall comfort and safety of the egg

1. how the egg reacts to the dangerous points in the situation

Helping the egg

Eggsercise 1:Driving

In this exercise we shall investigate the strength of the egg in an all too common dangerous situation – a car crash. We shall put the egg in a casket on the car and drive the car into a brick wall. From this we shall see what causes the egg to break, and then stop this happening in future tests.

Decisions

• the egg suffered as it kept moving when the car crashed, due to inertia. Therefore the egg must be restrained in the casket before safety can be assured.

• the car had no crumple zone and an inefficient bumper,

and so a crumple zone must be created

In this exercise we shall investigate the strength of an egg in another dangerous situation, but this time the forces acting on it will not be so great, they shall be acting on it from every direction. We shall put the egg in a boat and capsize it, and see how we can help the egg to escape this difficult situation.

Eggsercise 2:Swimming

Decisions• The egg would simply sink to the bottom if left in its natural state, therefore it is necessary to give it floating aids in order to keep it safely near the surface.

• However, in freezing conditions it is unlikely that the egg will survive even with a lifejacket, so we shall also equip it with an escape dinghy.

Eggsercise 3:FallingIn this exercise we shall

investigate the strength of an egg in a slightly less common, but all the more dangerous situation – falling from a great height. We shall drop the egg from a 3 storey building without a parachute to see how it fares, and then investigate the forces working on it to hopefully stop it from breaking.

Decisions

• the ground wasn’t soft enough for the egg to land safely, and so it would still break regardless of speed.

• the egg was going too fast, and its acceleration and velocity made too great an impact on the ground to survive.
