||To construct a vehicle powered by an
elastic band to carry a fresh egg over a 5-metre course in the fastest
time possible. (An alternative is to measure maximum distance travelled
rather than speed, but you need a lot of room.)
||To explore energy and motion.
||Teams of up to four.
A course 10 m in length with boards along the outside edge to
prevent vehicles leaving the course. A soft barrier will be set
up to stop the vehicles after they pass the finishing line. A
raw hen's egg weighing at least 60 g. An elastic band (e.g. Viceroy
#10). The vehicle can be constructed of any material, be of any
size, and must have been built by the team entering it.
- Each vehicle will be allowed 3 runs over the standard course
with the best time counted. OR
- Vehicles will run in pairs, with the winner proceeding to
the next round, until an overall winner is determined. A "double
knockout" system can be used to ensure each vehicle races
at least two times.
- The vehicle must self-start and must not be given any initial
impulse or have any external guidance at the start or during
- All the energy used to propel the vehicle must be stored
in the elastic band, which cannot be treated with chemicals,
heated or cooled in any way.
- One elastic band will be given to each team just before the
vehicle is stored until race time. At that time, each team will
install the elastic so that no alterations need to be made other
than winding up the elastic.
- The elastic band must remain intact, as one piece, between
the time of installation and the completion of the trial runs.
If the elastic breaks at any time during the competition, the
team will be disqualified. (Optional rule)
- Each team will receive an egg to be installed in the vehicle
just before the race. The eggs must not be altered or added
to in any way and must complete the course unbroken.
- Vehicles will start with their foremost structure at some
point in the first 3 m of track, as selected by the competitors.
- The race will be over once a vehicle completes the course;
however should a vehicle leave the confines of the track, interfere
with the running of a competitor's vehicle or stop and fail
to self-start, that car will be disqualified and the race will
be concluded (the other vehicle will be declared the winner
of that race).
- Each team will have a maximum of 9 minutes to run the trials
of their vehicle. At the end of 3 trails, the vehicle must be
functional so that it could run a 4th trial.
- Vehicles judged unsafe or hazardous will be disqualified.
- Each team must retrieve its vehicle after each trial run.
If the procedure results in breakage of the egg or damage to
the vehicle so that more runs cannot be completed without repairing
the vehicle, the team shall be disqualified.
- The 5-metre stretch used for timing the vehicle shall be the
last 5-metres of the course.
- The clock will be started and stopped when the leading edge
of the vehicle breaks light beams at the start and finish of
the 5-metre timing section of the track.
- The laser beams used will be 5.5 cm above the track
