OBJECTIVE
MATERIALS

Four
To build an original designed VECHILE (a car/truck/van) of
minimal weight and size which will keep two (2) medium
eggs from breaking from a height of 6.0 to 8.0 meters into a
target area (hula hoop).
Two (2) medium size chicken eggs and assorted materials as
noted below.
DESIGN PARAMETER
Only the following items may be used: The rules are (simulating the engineering challenge facing a
car designer).
‣ You can only use the materials listed below:
• 10 paper clips
• 100 standard straws (bendy is ok)
• string (10 feet)
• tape (only to connect things) Scotch
or masking tape only
• 2 egg carton cups
• 1 sheet of notebook paper 8 1/2 x 11
• 1 piece of foil (1 foot square max)
• 1 quart size baggie
• 4 rubber bands
• Elmer’s Glue
• NO more than one entry per team is permitted.
• All entries must be clearly labeled with names and school.
• Must fit through a standard basketball hoop in all directions. No matter which
direction it is turned.
• No parachutes or restraining devices may be used. The vehicle must drop and free fall to the
target area. The vehicle may not fly.
• The vehicle may not have wings.
• Students must be prepared to compute the volume of their container once the
Judge and the entry team have agreed upon a vehicle shape.
• Eggs must be placed into the vehicle at the site and in front of the judge.
• No kits may be used.
• Construction Goals.
1. The vehicle must be built prior to arrival at the MESA Day Contest Site.
2. The vehicle must have a door.
3. The eggs must be removable (i.e. not permanently attached)
4. Grade A medium eggs will be provided by judges to all contestants MESA Day, which
will be placed into the vehicle at the competition.
5. The vehicle will be measured and weighed.
6. No flying:
• No parachutes or lighter-than air balloons, or propellers.
7. A window must be provided 1 x 1 inch where the eggs can be seen during the drop.
8. Maximum size of vehicle:
• Must be able to fit through a regulation basketball hoop (provided by the
judges).
9. During the drop, the BOTTOM of the vehicle will be at the specified height.
• You will drop the vehicle on the judge’s signal.
10. The ground will be concrete covered with plastic on which is placed a hula hoop. The
hoop is the target area.

11. Do not use glue, tape, or string for building materials or structural members.
• These items are only to be used for connecting other things together.
12. You may cut parts apart such as straws or the plastic bag.
• Straws may not be used to reinforce other straws (placed inside of straws)
13. Bonus prizes awarded for best looking (successful) car and car with the smallest overall
mass prior to the drop.
14. Teams must submit a registration form provided by the host center. The form will have
school and team letter and team members name, type of vehicle constructed to hold the
egg, materials used to construct the vehicle.
JUDGING
• The eggs must survive.
1. Cracked eggs are NOT considered to be survivors (Cracked is defined as any egg that has
had its membrane ruptured. Membrane rupture will be tested with brown paper towels).
2. If there is a tie the lightest container shall win! Container will
be weighed with eggs. Each gram of weight is worth 10
points. The next tie breaker is the smallest container.
3. The vehicle must be identifiable as a car/truck/van
4. A successful drop must be with in the target area. If you miss
the target area 20 points will be deducted. If the vehicle
bounces out of the target area 10 points will be deducted.
5. If there is still a tie the Numerical Value for each container will be calculated as follows:
___S____
N = M+L+V
M= Mass (grams)
L= Longest dimension (cm)
V= Volume
S= Success factor (100 points for each egg that does not crack. 25 if eggs crack, 0 if really
broken)
