Egg Landing Competition Rules

1. The object of the competition is to design a device that will protect a fresh,raw large grade-A egg from breaking when it is dropped from a height

(Block C-Level 4). Entrants will compete to design a device with thelightest weight, the fewest number of parts, and the most accurate landingon the Drop Zone target

2. All scores will be determined using the Egg Drop Competition OfficialRules equations. The goal of the egg drop competition is to obtain thelowest non-zero score. Any egg drop that results in the egg breakingreceives a score of zero. All devices will be dropped from the same height.In the event of a tie in any of the categories or competition rounds, thetying entrants will continue to have their devices dropped until one deviceachieves a clearly winning score.

3. The first, second and third place winners from each category, as

calculated by using the equation, will compete in a final round ofcompetition for the Grand Prize.

4. Entry form can be obtained from the respective Physics teacher. Yourentry form must be received by your Physics teacher, on or before April26 , 2013 in order to be registered to compete. The competition will beheld on May 2, 2013.

5. Raw grade-A eggs will be provided on the day of the competition to eachcontestant, and are the only eggs allowed for use. Contestants shallprovide all other materials.

6. After the drop, the judge will remove the device from the target and thecontestant, or their designee, will remove the egg from the device for

inspection by the judge. No repairs will be allowed between drops.7. The entire device will be released at the drop plane (even with the top of

the railing). It cannot contact anything on the ground, a person, or astructure (for example, a long slide may not be used to transport the eggfrom the balcony to the ground.)

8. Participation is a team competition. Number of team members notexceeding two. Representative of each group will drop all devices.

9. After check-in, each device entered will be weighed with the egg providedto each contestant. No changes or modifications to the device will beallowed once it has been weighed with the egg. Once the device hassuccessfully landed without breaking or cracking the egg, the egg will be

removed and weighed; its weight will be subtracted to determine theweight of the device only, which will be used in the formula. Maximumdevice weight is 1000 grams (1 kg).

10.The number of parts used for each device will be counted. Each individualpiece will count as one part. For example, if the egg is cradled in 100Styrofoam peanuts glued together the device will have 101 parts (100parts peanuts and 1 part glue.) Gasses, other than air, will beconsidered one part.

11.The Drop Zone will be a target comprised of concentric rings. Landing theegg entirely within the innermost one-foot diameter ring will be one point,within the second ring will be two points, and so on. Landing outside all ofthe rings will be twelve points. The device will receive points based on theoutermost ring in which the egg lands.

12. Scores will be calculated using the following formula. If the egg cracks,your score is zero. The lowest non-zero score wins.

13.A panel of judges will determine if each entrant follows all competitionrules, and their decisions are final. Official rules are subject to change untilthe day of the competition.

14. The number of parts used in the construction of the device becomes afactor and the formula is:

W = Weight of the device in grams

N = Number of parts

DZ = Drop Zone Target points

EIF = Egg Integrity Factor (1 if not cracked or 0 if cracked)

FREQUENTLY ASKED QUESTIONS

Q: Do multiple uses of glue count only count as one part?

A: Glue can be used and counts as one part. Other adhesives can be used, but eachdifferent type of compound counts as a separate item or part.

Q: What about multiple uses of string? For example, if we use (8) 4" pieces of string isthat 8 separate parts? If so, then I'm assuming that if we do not cut the string but keep itas one continuous string serving to secure multiple sections then it only counts as onepart.

A: 8 pieces of string would count as 8 different parts. One long continuous piece of string(or tape, or other item) would count as one part, but may add additional unneededweight to the device; the choice is left to the entrant.

Q: For decorating the device, does the ink count as a part?

A: Coloring would not count as a part, but may affect the weight of the device. Decals orother additional identify in insignia (ribbons, flags, etc.) will count as additional pieces asthey can affect rigidity and accuracy.

Q: Is there a maximum weight of the device?

A: Yes. The weight of the device, without the egg, cannot exceed 1000 grams (1 kg).
