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 of 21.5 feet. Entrants will compete
to design a device with the lightest weight, the fewest number
of parts, and the most accurate landing on the Drop Zone target
(see equation at the end of the rules.)
All scores will be determined using the Egg Drop
Competition Official Rules equations. The goal of the egg drop
competition is to obtain the lowest non-zero score. Any egg
drop that results in the egg breaking receives 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, the
tying entrants will continue to have their devices dropped until
one device achieves a clearly winning score.
The first, second and third place winners from each
category, as calculated by using the equation, will compete in a
final round of competition for the Grand Prize.
There is no entry fee; however, on-line registration is
required. To register for the competition, enter on-line at
www.wsfceggdrop.com. Your entry form must be received on or
before February 16th, 2010 in order to be
registered to compete. Registration is limited to the first
400 entries. Only one entry per participant is
permitted, and each device can only be entered in one category.
Large raw grade-A eggs will be provided on the day of the
competition to each contestant, and are the only eggs allowed
for use. Contestants shall provide all other materials.
After the drop, the judge will remove the device from the
target and the contestant, or their designee, will remove the
egg from the device for inspection by the judge. No repairs
will be allowed between drops.
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 a structure (for example, a long
slide may not be used to transport the egg from the balcony to
Participants must drop their own devices. If they are unable to
reach over the railing, they
present at the drop but may appoint someone else to drop the
device for them.
After check-in, each device entered will be weighed with
the egg provided to each contestant. The lowest weight for a
device will be zero (no negative values will be allowed.)
No changes or modifications to the device will be allowed once
it has been weighed with the egg.
Once the device has
successfully landed without breaking or cracking the egg, the
egg will be removed and weighed; its weight will be subtracted
to determine the weight of the device only, which will be used
in the formula. Maximum device weight is 1000
grams (2.2 pounds).
For the Grand Prize competition, the number of parts used for
each device will be counted. Each individual piece will count as
one part. For example, if the egg is cradled in 100 Styrofoam
peanuts glued together the device will have 101 parts (100 parts
peanuts and 1 part glue.)
Gasses, other than air, will be considered one part.
The Drop Zone will be a target comprised of concentric rings.
Landing the egg 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 of the rings will be
twelve points. The device will receive points based on the
outermost ring in which the egg lands.
Scores will be calculated using the following formula. If
the egg cracks, your score is zero. The lowest non-zero
initial round, the formula is:
For the grand prize round, the number of parts used in the
construction of the device becomes a factor and the formula is:
W = Weight
of the device in grams
N = Number
= Drop Zone Target points
EIF = Egg
Integrity Factor (1 if not cracked or 0 if cracked)
The cash value of the prizes, awarded the day of the competition
in each category, shall be:
Grades K - 5
Grades 6 - 8
Grades 9 -
Teams – all ages
You must be present at the end of the competition to win.
A panel of
judges will determine if each entrant follows all competition
rules, and their decisions are final.
Official rules are subject to change until the day of the
FREQUENTLY ASKED QUESTIONS
Q: Do multiple uses of glue count only count as one part?
Glue can be used
and counts as one part. Other adhesives can be used, but each
different type of compound counts as a separate item or part.
What about multiple
uses of string? For example, if we use (8) 4" pieces of
string is that 8 separate parts? If so, then I'm assuming that
if we do not cut the string but keep it as one continuous string
serving to secure multiple sections then it only counts as one
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 unneeded weight to the device; the choice is left
to the entrant.
Q: For decorating the device, does the ink count as
Coloring would not
count as a part, but may affect the weight of the device.
Decals or other additional identifying insignia (ribbons, flags,
etc.) will count as additional pieces as they can affect
rigidity and accuracy.
is the weight of devices using lighter-than-air gasses (i.e.
helium balloons) measured?
weight of the helium, the balloons and attaching string or
straps is negated by the uplift of the helium; however, those
items do have mass. Any device using helium shall be weighed
and the volume (length x width x depth) of the balloons shall be
measured. For every liter (61 in3) of balloon volume
we shall add 0.18 grams for the weight of the helium and 1.07
grams for the offsetting uplift (a liter of air weighs 1.25
grams) to the weight measured by the scale to determine the
total device weight.
there a maximum weight of the device?
Yes. The weight of the device, without the egg, cannot exceed
1000 grams (2.2 pounds).
