To anyone who may help,

Some of you might be familiar with the Science Olympiad Competition where
students in middle school and high school compete in a team with other schools
in their state, and other states, when they qualify for the nationals. One of
the events is the Scrambler. This event asks students to come up with a vehicle
that after being launched from a student built launcher, stop  at a distance
between 8-12meters(which will be determined at the competition) orelse it will
break a raw egg at the front of the car. The goal of this event is to make a
braking system that will allow the vehicle to stop at any distance between
8-12meters and not go over the finish line too much or not go over the finish
line at all without cracking a raw egg at the front. Any of you have any
suggestions for a braking system? What I really want to ask is where can one
find light, small wheels(less than 6in in diameter and have good traction).
One more note, the vehicle and laucher must be contained in a 1mX1mX1m cube, so
the vehicle has to be small(so it could be fast, which is counted as part of the
score)

Looking forward for any responces.


PS. Just to make myself clear, I have already a breaking system, but I would
like to know what others could think up, and I need to find wheels.
