How to Make an Egg Survive a 20-Foot Drop

Save

Successfully dropping an egg 20 feet without it breaking is a project for science students of all ages or an experiment you can try at home to demonstrate the principles of physics. The challenge is to use materials to protect the egg from the impact of the fall. Check with your teacher for rules and limitations if you are trying the drop for school, such as what type of materials and containers you are allowed to use. Be creative in the materials you use, as well as the methods of protecting the egg.

Things You'll Need

  • Plastic, sealable bags
  • Raw egg
  • Cereal
  • Plastic, sealable container with lid
  • Place one raw egg in a plastic, sealable bag. Fill the remainder of the bag with cereal. Any type of cereal will work, but puffed types are best since they are less dense than flakes and provide greater surface area to absorb impact. Seal the bag.

  • Fill four other plastic, sealable bags with cereal and seal them.

  • Place two bags filled with cereal only into a plastic container. This provides a bed of cushion for the bag with the egg inside.

  • Place the bag with the egg inside on top of the two bags filled with cereal.

  • Add the remaining two other bags with cereal inside to the container on top of the bag with the egg inside. There are now two bags underneath and two bags on top of the egg bag.

  • Seal the plastic container.

  • Test the drop by climbing onto a rooftop using the access stairs near the top floor of the building. Choose a roof with railing to prevent falls.

  • Drop the container with the egg onto the ground below. Make sure no one is in the area where you drop the container.

  • Descend from the rooftop using the stairs inside the building and walk outside. Find the container with the egg inside and open it to see if the egg survived.

  • Repeat the process with another egg if the first did not survive the initial drop. Clean out the container and the plastic, sealable bags before refilling with new materials.

Tips & Warnings

  • Experiment with alternative materials by padding the egg in styrofoam cups, nylon stockings, liquids or other soft substances.
  • Always use caution on rooftops and at elevated heights. Test the egg drop experiment with a person you trust in case of emergency.
