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.
