What Is a Good Egg Drop Design?

A good egg drop design entails constructing devices from materials that can include styrofoam cups or plastic bags with cereals, notes WeirdScienceKids.com. For a successful egg drop design, the built contraption must protect the egg so that it does not break when thrown from a specified height. In physics, egg drop experiments are useful for teaching students about gravity and momentum.

There can be very basic egg drop designs, such as placing sufficient layers of paper towels as cushioning materials for the egg. MarshallBrain.com demonstrates this experiment, which requires at least 30 layers of paper towels to absorb enough energy so that an egg dropped from a height of two feet does not break.

However, there are more complicated egg drop designs that can entail building a protective container for the egg from straws, ice-pop sticks and tape. This experiment requires that the egg be dropped from 10 feet, notes PBSkids.org.

Another egg drop design requires the use of simple materials that include plastic bags and cereal. For this design, students place an egg in a small plastic bag, add cereal to the bag and seal it. Cereal also is placed in four more small plastic bags. In a large plastic bag, place the four sealed small cereal-filled bags in a larger bag and then put the bag with the egg in it in the middle of these other four bags. The four bags should protect the egg from breaking.

Another popular egg drop design uses Styrofoam cups, tape, a small rock and an egg. The complete instructions for this egg drop design and the use of plastic bags are provided at WeirdScienceKids.com.
