the smell of success should NOT be the smell of eggs! - Unit 7

For this project, I was assigned to my partner Nalei. When we came up with an egg catcher, we agreed that in order for there to be less force on the egg (so it won't break), we had to somehow increase the contact time, and decrease the the impulse.

What we did: We used a plastic container and cushioned the bottom and sides with shredded newspaper. There are about ten sheets of newspaper on the bottom of the container, so there is something between the hard plastic and the shredded newspaper. Towards the middle of the container, there is a cup of cotton balls surrounding the egg. The egg is wrapped in one sheet of newspaper, and is sitting on the cotton balls. On top of the wrapped eggs, there are more cotton balls and newspaper.

What we used:
1 plastic container 23 cm in height, 13 cm in width, 17 cm in length.
20-30 cotton balls
15 sheets of newspaper

Why we did: The four inches of newspaper were supposed to cushion the eggs landing, and create a separation between the egg and the plastic. The cotton was supposed to increase the contact time, as well as create more of a cushion. Wrapping the egg in newspaper was supposed to protect the egg more.
...success?








No, I failed. A lot of the mass came from the lid of the plastic container, which we weren't expecting to land on the bottom. The lid split open, and the egg couldn't handle all of the force.
