The key to a successful egg drop experiment? Drop it on its side

Egg drop competitions are a staple of high school and college physics classes. The goal is for students to build a device using bubble wrap, straws, or various other materials designed to hold an egg and keep it intact after being dropped from a substantial height—say, 10 meters (nearly 33 feet). There's even a "naked egg" version in which a raw egg is dropped into a container below. The competition is intended to teach students about structural mechanics and impact physics, and it is not an easy feat; most of the dropped eggs break. MIT engineering professor Tal Cohen decided to investigate why the failure rate was so high and reported her team's findings in a paper published in the journal Communications Physics. "The universal convention is that the egg should be in a vertical orientation when it hits the ground," Cohen told Physics Magazine. But their results from controlled trials simulating the egg drop challenge in the lab calls this conventional wisdom into question. It is no ... Read full article.
