I added a section to the Mousetrap Vehicle wiki, on how to build a vehicle in one night. Hope this will be helpful! :arrow: :mrgreen: :roll: 8-) ;) :D ;) :shock: :o :oops:

Hey, what are you guys finding that works the best for wheel grip on CDs? I am using electrical tape right now, is that good?

That should be fine, but I personally prefer latex balloon strips.

Is there an advantage for using latex strips?

I'm not sure, although I would think that they will have a better grip.

Oh, you actually don't have to purchase them. Just take a regular old balloon (not the shiny helium ones, but the normal rubber ones) and while holding it flat on a table (no air in it), cut a horizontal strip about 1 inch wide from the center of the balloon. Once you do that, you'll have a loop/ring. Just put this over the outside edge of your CD's.

When you make your vehicle faster where do you attach tape to? The whole back axle? Parts of it?

You can do the whole axle if you want, but it's unnecessary. Just put tape around the areas that the string will actually wind onto. On our mousetrap from last year, it was about a two inch long area in the middle of the axle. Using less tape decreases weight.

That's called a Pull Arm. The easiest way is to simply zip-tie it to the mousetrap and then maybe reinforce with hot glue. This is rather robust and also allows for easy removal if necessary.


I'm using some clamps...not exactly sure what they're called but they're U-shaped and then they go through some sort of holding device and are attached with washers... I used them to clamp the rod onto the arm of the mousetrap... I'll find out the name of the clamps, sorry I didn't know! :(


thanks for the help guys :D

I need help making my car going the distance... I've read the wiki and so I've changed the lever arm's sizes. I made it lighter. What else can I try?

Check the amount of friction the string has while the arm is pulling, this was the problem with the one I had originally and because the string was subject to so much added resistance the vehicle had trouble traveling a few feet. You should also check how freely your wheels spin as well; a little lubrication on the axil may allow them to spin easier allowing for a greater speed thus allowing for more distance. The "tread" material for the wheel may be too effective and providing too much friction with the ground or too little causing the wheels to slip on the ground causing the vehicle not go travel its maximum distance. How massive is your vehicle a mousetrap provides so little force that ~1lb is a good target weight if your vehicle is currently heavier than that.
