Crumple Zone:
Identify the Problem:
-Create a Crumple Zone which can have the least amount of weight, with the greatest amount of shock absorption.
Generate Ideas:
-A cone to take in the pressure of the weight.
-A set of springs which would go against the weight and push it down.
-A sponge which would have a very large surface that would take in most of the force.
Constraints:
-We can only use paper and staples.
-The area of the crumple zone can be no more than 4" x 4" x 4" and no smaller than 2" x 2" x 2"

The Idea Matrix (below):
Research:
-We built the Cone, and the weight crumbled it.
-We also built the Springs, but they did not work under the force of the weight.
-We then built the Sponge, the weight almost deflected and make the Sponge bounce back.
After reading the information about Crumple Zones, we tried to recreate the cone, but the item still failed. After reading a bit more and going into a little bit more depth about Crumple Zones, we made a Square with rolled and coiled up manilla papers in it, but as a group we soon realized that the Sponge had more Surface Area than the Square so it was more effective in that manner.
Possible Solutions:
The Sponge would be the best choice, not only does that our data support our claims, we as a group noticed that the Sponge was more stable, efficient, performs best, and is most effective.

PRACTICE TESTING:
-Our design completely failed, the crumple zone did not absorb the impact and it did not crumble at all.
-The egg completely cracked and half...
-Our design did not work and we are planning to make a whole new design.
-Our weight for our original crumple zone was 55 grams.
RE-DESIGN:
-Our new design will be quite different from the other one.
-This design will be a cylinder with paper scraps, one spring that was vertical. This is called the "trash can".
-Everyone in our group will think this will work and hopes for the best in the final test.
Summary:
-Our practice testing didn't go as planned.
-The idea of a crumple zone is a great idea.
-It protects the subject that is going to be hit.
-I wasnt here for the second testing for the crumple zone due to my trip abroad, but my group mates said that our re-design worked great and no cracks in the egg were recorded.
-If i was going to make a third crumple zone, I would make a cube with a lot of paper stuffed in it for lots of support.
-I wouldn't really change the assignment because I really enjoyed it.
