12) Today we tried out our new design from a height of 4.5 meters. It worked fine however the lid fell off a little, so to prevent this we aded some tape to it. Unfortunately, because of a misunderstanding our preferred design did not comply with the rules.  This is our final model and hopefully it will work on Monday!
- Height: 11.5 cm
- Width (diameter): 10 cm
- Weight: 0.2 kg

9) Today (Wednesday March 5th) we tried to modify our cone model by cutting a sliver at the top of the cone and adding a paper to keep the egg on top and allow it to fall back down as soon as release. This however did not work our well. Thus, we decided to start a new design keeping a few of the characteristics of our past cone model in mind.

10) In our new design we decided to use an aluminum can (because it is light and strong). Then we also added layers of toilet paper on the bottom and on the sides until we had put enough for the egg to be at the top of the can and slightly above the edge. The tissue helps cushion the egg and hold it in place to try and lower the effect of newtons law of motion/inertia, and thus prevent it from continuing in the same direction and breaking.

11) Then by heating a nail we opened a hole in the lid of the can so that a small part of the egg may protrude and therefore comply with the rules.

8) Today (Monday Feb. 3rd) we were informed in class that there had been a misunderstanding with the rules. Apparently the egg had to not only be visible but also be "the closest thing to the moon of our design" which basically meant our model no longer followed the requirements and would be disqualified. We had 2 options: 1- Try and and modify our design so that the egg would be at the top of the cone before release and fall to the bottom of the cone once released (to maintain a good center of gravity).--OR-- 2 - Start a new design with 1 week left before our deadline. 

6) Today (Wednesday Feb. 19th) we met to make our second experiment and try out our new design which we planned on Monday. Aside from shoving the egg down deeper we also decided to cut out and add the the egg holder piece from the egg carton to help keep it in place. This is what our model looked like.

7) The drop was a success!!!! Even though we dropped it from a tremendous height (11th floor), the egg had survived. It had a small crack but there was no yoke leaking out. The crumpling worked perfectly to cushion the egg and absorb the shock of impact. If it worked at this height it will work anywhere!

3) Today (Monday Feb. 17th) we met to construct our model and make our try it out for the first time.

4) When we dropped our design it flipped over and fell head first, therefore the cone did not crumple and the egg splattered all over the floor.

5) The feedback we got from our experiment was very constructive. We found out that because the egg was at the top of the cone it had a terrible center of gravity, thus allowing the smallest amount of wind to tip over the model. We decided to shove the egg deeper into the cone so that it had a stronger center of gravity (like the Rooney vs Crouch example). Since the flaps didn't seem to help much we also decided to remove those. Here is our new blueprint.

1) Today (Thursday Feb. 13th) we met to brainstorm and decide what we would like our design to look like. First we thought of all the different attributes which might help our model perform its best. We drew ideas of what we believed to be these most important and effective characteristics.

2) After thinking about these different traits that we would need to incorporate into 1 design, we came up with our final model. We drew a blueprint of it explaining the different features. - We concluded that it would have a cone for aerodynamic purposes so that air could flow equally along its side and therefore cause the model not only to be fast, but also to NOT curve or flip (like tennis ball topspin example of unequal airflow).

- We made the design out of paper so that it would weigh less (a quality that is taken note of to win); and also to have less Gravitational Potential Energy, thus lowering the amount of energy that must be conserved when it makes impact.

- The purpose of the coned bottom is to crumple up absorb the shock so the egg won't break

- We added flaps to the model to help prevent it from flipping.

- We decided to add tissue or foam around the egg so that it would stay put once the cone hit the ground. If we did not do this, then according to newtons law of motion/inertia the egg would want to continue in the same direction and break.
