Egg Drop Competition Day!

The mass of our container on competition day, after our modifications, was 137.0 g. The containers final dimensions were 27cm/26cm/11cm and dropped from five meters in 1.07 seconds. Our drop was successful, scoring us a perfect 10. Our egg points were calculated out to be 146. I believe that the parachute rule really prevented our container from its full potential. With a parachute attached to our container, you could drop it as many times, and as high as you want and it wouldn't break. I think that the most effective part of our containers design was the flaps. The flaps allowed stabilization during the drop and also slowed down the fall. I don't really see any weaknesses in our design overall, every part of the container was essential for the success of the drop. If I were to carry two eggs I would alter our design by cutting two holes in the toilet roll and i believe that it would also help stabilize the container during the fall.

Egg Drop Test Day!

During testing day we used our design of a box inside of a box and took it to the top of the math staircase to try out our design. It failed, miserably. We decided to give up on that design and start from scratch once again. The next day we came back with a design that consisted of a roll of toilet paper with a hole cut into the side that would hold the egg. It was then wrapped in a sock to prevent the toilet paper roll from falling apart and to add extra cushioning. The whole in the toilet paper provided a tight fit and that prevented the egg from moving around on impact. We took that design back to the staircase to give it another shot, and passed! We decided to give it another go just to make sure that it was consistent. The second drop failed. After being baffled about why it failed the second time, we realized that it was very important to fluff up the bottom of the toilet paper to make sure the egg had a lot of material beneath it to cushion the blow on impact. Some things that we changed before the actual competition day were adding "flaps" or "wings" to our container to slow down the falling speed and keep it stable in the air while being dropped.
