Last Wednesday, just before Thanksgiving break, our class held our "egg drop". My partner was Kanoe Sakamoto and our assignment was to create a capsule that could contain an egg and protect it from being broken after being thrown 3 stories from Akahi dining hall. So to begin this project, I honestly had no idea how to start. In 5th grade we did the same type of thing but our capsules could use parachutes, these ones couldn't. Therefore, because I was unsure of what to use to make this experiment successful, I decided to do a search on Youtube for ideas. I came across one girl who used three sponges, hiding the egg within a middle sponge and connecting all three using string. This mechanism worked for her, so I figured I'd give it a try. So I bought the supplies and tested my recreation and it worked!(: With that being said, my egg drop was a success, keeping my egg from breaking when thrown 3 stories. The lightness of the sponges kept the egg from falling at such a high velocity, increasing its contact time with the egg, decreasing the capsules linear momentum. I really liked this experiment, just because it was an interesting way to learn about momentum hands on. But yes I got my idea for this experiment from youtube, but its not called cheating, its called working smart, not hard (:

Your sponge idea was really smart! I hadn't even thought of using a sponge. Great job and congrats on the success of your egg drop(:
ReplyDeletegreat blog lehua! I thought you design was CHEAT! but it worked so i guess it was good hahahah! i enjoyed reading your long write up!
ReplyDeleteYour design was very smart, and easy to make. Wish we thought of something that smart! Good job!
ReplyDeleteI think your guys' device was the smartest-built device in our class! It was light in weight and had lots of cushioning! Good Job
