My group and I named our Egg Spaceship DJ-Z.

For our Egg Spaceship, we used water balloons filled oxygen, marshmallows, butter, and glue to help the egg not break. These are the reasons why we used these materials.

Water Balloons filled with Oxygen: We used this material to help our eggs stay unbroken because the water balloons filled with oxygen are smushy. This would help the egg from hitting the floor really hard, but instead hit the floor a little softer. The egg hitting the ground is an example of **inertia**. Inertia says that an object that is in motion will stay in motion until an external force acts upon it. The ground in this example is the force that acts back. This is also **action-reaction**, because gravity pushes spaceship downwards, but the floor pushes the spaceship upwards.

Marshmallows: We also used the marshmallows for the same reason we used the water balloons filled with oxygen, because the material is mushy and soft. This makes sure that the egg doesn't hit the hard ground. Especially since **gravity** is the reason that the egg falls down, and the heavier the spaceship is, the more gravity will act upon it.

Glue: We used the glue to make the marshmallows stick to the sides of our spaceship. We did this incase the egg hits the sides of our spaceship, so that it would hit something smushy rather than something hard.

Butter: We used the butter to make the egg slippery, so that it when it hits the balloons and marshmallows, it will be slippery too. It would help the egg survive and not break.
