CrashCar Eggspert

Each team will build a structure on top of a PineCar Racer. The structure will be designed to hold and protect one or two eggs as the car is rolled down a progressively steeper series of ramps and crashed into an immovable barrier.

Are the kids allowed to bring an egg carton to keep the eggs safe from the time received, to the time they have to do the ramp runs?

Yes, they are allowed to bring anything, but it should fit on the build tray that is provided.  A half-dozen egg carton can fit in the tray and would be a good choice.

When exactly does the 20-minute timer start? Do the students get their materials first?

Before the timer starts, the students receive their build kits and are asked to confirm the contents.  The Supervisor will also let them know what is eliminated.  The students should know the appropriate quantity of each item in the kit, and can request to replace any missing or damaged items.  This happens pretty quickly.  Once the timer starts, exchanges or replacements are not allowed.

Must the egg not be wrapped, covered, or attached to the car using the given material? It will merely"sit" in the cage built? Can it be wedged in between the given material?

The egg should not be wrapped or covered. Egg should be able to come out of the structure as a free fall after the run of each slope to ensure its not leaking.

Is it acceptable for the egg to free fall from the back of the structure or is it required that the egg falls out from the top of the structure?

It is acceptable for the egg to fall from any direction provided it is a free fall.

See the "Egg Extraction Rule" video posted above.

Will we know what will be in the bag before the build time?

The possible list of materials is listed in the rules.  The few materials that are excluded will not be published ahead of time.

May the students use all 20 mins for construction?

Yes, they may.  Be aware that the construction time is an important factor in scoring. It is common for the build time on this event to determine rank order among team scores.


May the students stick the 1/4" self-adhesive stickers to the egg?


The rules require that the egg must fall freely from the device (i.e., separate entirely) when inverted, and stickers on the egg would not do that.

With 2 eggs can students hold back an egg so that only one egg is extracted at a time?


See "The Egg Extraction Rule" video posted above.

At the competition, do the students get their eggs before or after the timed build?

Students get the eggs at the same time they get the Kit, before they start building.

If a wheel falls off during one of the races, is the car disqualified or can it still run the next ramp?

 No repairs can be made; but the car is allowed to attempt the next ramp 'as is'.

Will the "up to 3 items" be removed when they get their supplies before they start building?

Up to 3 items will be omitted from the build materials they are supplied.  There will be a printed list of the materials identified in the rules, identifying which materials are missing.

Students should survey their materials and alert the supervisor immediately if anything is missing BEFORE THEY COMPLETE THEIR BUILD.

There were items omitted from build materials at the District practice competition. Will these same items be omitted at the Macomb county competition?

Likely no (but possibly –yes).

Students will not be sure of the materials until they begin to build their car.

Do the eggs have to be in a line one after another, or can they sit side by side?

You may place the eggs in any orientations, driver first or passenger first, side by side or in line.

When are the eggs marked as driver or passenger?

Marking of the eggs is done before the eggs are handed over to the team.
