Alvin's Sports Car 2007

Hi! My name is Alvin. I have been participating in the HKIS summer course this holiday. This course-Machine Mania-involved inventing cool racing cars, doing interesting experiments about static electricity, different gears and other stuff about machines. Although my finished car won't be as pretty as the neat sports car above, it will still race my classmates' other cars on the last day of our course.
Here is a quick introduction of my car: It is made of a main foam core board, and is powered by two mini motors with two 9v batteries. It also uses different kinds of gears to power the wheels, which are connected with two metal axles. When you flick the knife-switch, the car will zoom off. There are 3 types of tracks to choose for the car on the race day: flat track, uphill or SUV. I am planning to race on the flat track, because my car's designed to race on flat surfaces. Going uphill is its disadvantage, and I think that SUV is too hard for it. So, flat track is my car's right track.

This is the result of the race.

My best time: 10.81
My friend's best time(flat track): 17.04
