Mouse Trap Race Cars

This is the 3rd Annual Mousetrap Racecar Challenge yet it is my first time participating in it. I had a great time with it, with my partner Brett. He was the photographer for both video and immages.

For the front wheels we used CD to redse drag. Each one was held on by two smaller wheels that kept them in place for the most part, they had to be adjusted every now and then. We added a small metal rod to the mouse trap "bar" to increase the length of the lever arm. The rear wheel had the power and had a rubber ring around it to increase traction. We used a total of 35 parts, thats counting every little piece. We got third palce in the distance race and second in the speed race.

Total Points: 10

Design Stage:"Brainiac" -

"Visualize It!" -

Build Stage:
"Build It" -

"The Price of Glory"
- we would have spent $35 on our car, witch is not that much considering that the formula 1 cars can cost upwards of hundreds of thousands of dollars.

"Competitor" - yes we did
"Feedback" - Collect feedback (at least one each of +, change, ? and !) from yourself or your classmates.
?- Why did it have CD's as wheels?
  -Did the CD's help alought or did they not make a difference?
Change- I would have changed the rear "power axel" so that at the end of its run the string would slip off and not tangle up again so that it would stop itself.
+- The CD's make it look really cool.

Iterate Stage:
"Re-work"
-Between our first and second races we added a strawl on the end of the lever arm to extend the length but not the power.

"Game Changer"
-I would change the limit on the tape so that you could use any kind of tape and however much tape you wanted to use. I would do this becasue I found it extreemely hard to do every thing i wanted to do with the limited amount of tape that I had at my disposal.

"Name it"
- Invent a name for an achievement that you think is better than what we have currently.


"Leave It Cleaner Than You Found It" - yes, all the tape we used was thrown away and the piecses we used were put away
