Mike McKee
Director, Florida Science Olympiad
Chair, National Rules Physics Committee

2. Naked Egg Drop Goal: Design a package to prevent an egg from breaking.
This is an engineering event.
Students should test and modify their design prior to competition.
This is an IMPOUND event.

3. Naked Egg Drop List of Possible Materials: Paper cups Drinking straws
Popsicle sticks, wood splints, etc.
String
Masking tape
Rubber bands

4. Naked Egg Drop
When the egg is given to the student, make sure they check for cracks before the judge walks away.
Students may bring 2 pairs of scissors, ruler and 1 pair of pliers ONLY.

5. Naked Egg Drop Drop height: A plumb line will be provided.
Announced prior to construction
3-4 drop heights
Students will move device
A plumb line will be provided.

6. Egg Drop
Scoring: Greatest Height Egg Survived (mm) – Height of Device (mm)
Ties are broken by time. Team with the lowest competition time is given more favorable score.

7. Egg Drop Broken eggs are scored below all those that do survive.
A broken egg is defined as one in which a wet spot can be seen on a paper towel.

8. Egg Drop Construction Hints:
Use crumple zones. (Sacrifice the package.)
F=ma – Impulse and Newton’s Second Law.
Use smart engineering.
Go wide, not deep
