Purpose: The objective of the project was to build a structure capable of bringing the egg safely to the ground without harming or damaging the egg in as little material as possible.
Equipment:
One larger bottle
One smaller bottle
One red balloon
One blue balloon
Too much tape
Procedure: The procedure to make the device was as simple as cutting two bottles in half so that you may then stretch the balloon over the opening that you have created. This is where the egg will rest during the fall. Measuring the device we placed it on a scale to see exactly what its weight was, which turned out to be 76.5Kg. The dimensions of the structure were measured with a ruler using the centimeter side. The dimensions came out to be 9cm x 9cm x 24.5cm. Just below the maximum height. Testing the fall, we took the egg and the structure over to the rotunda to drop it from about 5.3 meters. You would then be judged on how or if the egg survives the fall and given a score that fits well.
Data: The dimensions of the structure are precisely 9cm x 9cm x 24.5cm. The weight of the object is 76.5Kg.
Data Analysis: During the fall the bottles tilted more than expected to due to not having enough weight placed on the bottom and the center of gravity being off a bit. This resulted in the breaking of the egg.
Conclusion: The things I would have done differently are that I would make a more stable structure so that the egg would have a smaller percentage of breaking or dismantling. Otherwise, I would have made it so that there was more weight near the bottom so that the bottle would not tilt so much during the fall causing the egg to land on its side and break. Some questionable results I got were that the material completely absorbed the shock of the egg for the most part, and then if the egg would be harmed during the fall. Changes in design for a higher drop height would include a more stable
