Science teachers often assign the classic egg drop experiment to middle school and high school students. This experiment is designed to teach students about gravitational and kinetic energy. Experiment with different materials to determine what will prevent eggs from breaking. Students can make a crate from straws and rubber bands for this experiment.

    Drinking straws wrapped with rubber bands protect the egg.

    Loosely wrap a rubber band around the egg. Gently stack the straws upright between the rubber band and the egg. Do this around the entire egg to create a crate. It helps to have a friend assist you.

    Go to a stairwell, rooftop or window. Let the egg drop. Unwrap the straws and rubber bands and check to see if the egg is still intact.

    Conduct the experiment more than once if necessary

    Conduct the experiment again if your egg broke. Add more rubber bands this time. Add another layer of straws for a thicker crate to cradle your egg.

    Things You'll Need

    • Uncooked eggs
    • Drinking straws
    • Rubber bands
    • Helper

    Tips

    • Try dropping the eggs from different heights. Keep a chart for your findings. Have a contest to see who can build the best protective crate for their egg.

    Warnings

    • Be sure to clean up any mess quickly because dried egg can be difficult to remove when it hardens.
