My partner, Sean Lee, and I, competed against the class last week in the Second Annual Egg Drop Challenge. We used an awesome elevator design, which involved a plank that leaned over the edge, taped it down and added counterbalances to the other side, so it would not fall, hurting someone. It also involved a long piece of string, a small cardboard box, more rocks, a ton of dominoes, a lot of duct tape, and socks. We used the box as a container for the egg, and inside we had a sock as a cushion on the bottom of the egg, and we used the other sock for a top cushion. We used some of the dominoes inside the box with the egg in order to create more weight in the box. On the other side, we used duct tape to make a counterbalance with rocks, slightly heavier, probably 10-15 grams more, than the box with the egg. We used the string to attach the two parts (the box with the egg/counterbalance) and then we let it go on the plank, and it slowly, safely, and surely lowered down to the ground without the egg breaking. We earned a lot of achievements, listed below.
