Egg Drop Experiment

Egg drop experiment: Julie

Inspired by the Ignite Seattle challenge and Bre Pettis’ blog posts, the girls and I decided to try our own egg drop experiment even though we couldn’t make it to the meeting on Tuesday night.

First I got out the shipping box I had received from Apple with my MacBook repairs and I let the two older girls create their own contraptions with those egg crate and blue foam packing materials plus lots of duct tape. I figured anything Apple was using had probably been proven effective in various drop situations.

I also thought it would be fun to use ordinary household objects. So Elisabeth and I stuffed an old baby bath sponge inside a Lego container. She packed the remaining empty space with washcloths. For a fourth experiment, I did a little reading online (while trying to research how to do the actual drop) and decided to try popcorn packed inside an empty (sugar) carton.

We didn’t watch Bre Pettis’ video until after we had dropped our own eggs. As always his creations and ideas are inspiring. He also included a simplified equation that could be used to calculate the speed of the egg. Since our drop was 8 feet, the egg reached a speed of 15 miles per hour on its way from our deck rail to the concrete outside our garage.

The girls made the suggestion so I made fried rice for dinner: we ate the three eggs that survived the drop.

End of the Egg Drop Experiment: Fried Rice

For more details, please watch our video! The girls each describe their creations and then we discovered which ones would survive the fall…

I can’t wait to try this one again. It’s fun and educational. And as Bre suggests, a great thing to do as a group. Thanks to Ignite Seattle for the inspiration!

    How fun! Thanks for the cool video. I loved watching it. It’s interesting to see your kids’ different personalities through their interviews. This post makes me hungry!

    I like how Abigail used her imagination to design and Michaela used tape and foam. How funny!
