Many students get excited about the prospect of needing to design an egg catcher for science class. The building and testing phase can be fun, yet the students learn so much about physics in the process. A project like this makes science fun and exciting. There are many different ideas on how to build an egg catcher. The egg catcher cannot be over a certain size, or the egg cannot be completely covered. These instructions are for a basic egg catcher, but can be modified if needed.

  1. 1

    Open the top of the milk carton fully by pulling apart the sealed top.

  2. 2

    Cut a small piece of pipe insulation to fit into the bottom of the milk carton. This will be about 1.5" x 1.5". Place this into the bottom of the milk carton.

  3. 3

    Cut another piece of pipe insulation big enough to wrap one time around the raw egg. Wrap this around the raw egg and place the egg inside the milk carton.

  4. 4

    Cut a piece of pipe insulation to fit over the top of the egg. This will be about 1.5" x 1.5". Place this piece of pipe insulation over the top of the egg.

  5. 5

    Close the milk carton by folding the pieces back the way they were and press the folded area down flat creating a square or rectangle shape to your egg catcher.

  6. 6

    Wrap the milk carton with several rubber bands to keep it closed. The rubber bands will also allow the egg catcher to have some bounce to it, which will lessen the impact when the egg catcher hits the ground.

Tips and warnings

  • You can use any size pipe insulation that you wish. Typically there are two types, one is thicker than the other. If need be the thicker can be cut down to fit into the carton, or the thinner can be doubled up.
  • Be sure to test your creation from varying heights several times before the big egg drop day, you don't want to find out too late you didn't use enough rubber bands or that your pipe insulation wasn't thick enough.
