Step 1: Supplies

I used the following:

A mouse trap
4 eye hooks
6 balloons
2 bic pens (the smooth kind)
2 tops from pop cans (for the serious perhaps washers, or otherwise any other bendable metal)
some string (not pictured)
4 CDs/DVDs (expendable ones). Here 3 CDRs and a blank transparent thing from the top of a spindle. I hear DVDs are a bit lighter, but I'm not optimizing that hard.
Nice. I made one of these in my Engineering class a few months back. My team did pretty... bad. We got stuck with two know-it-all sophomores, a girl who was afraid of tools, another girl who just wanted to get her math homework done that she didn't do the night before, and me... the shy, quiet girl who had ideas but couldn't voice them. D: (Haha, I'm not trying to make my team look bad, by the way. We all became friends because of that project. xD)
Oh, also... This is what we ended up with. (The first image is my design. We tried to follow it but somehow ended up with... the second image. >.<)
<p>Beautiful art work.....</p>
<p>i didnt made anything . but i hope people could show me there images so i casn have a idea</p>
<p>cool i like how you made the mouse trap car</p>
<p>Sick invention :D I laughed honestly ! Very cool </p>

<p>im making one for science class and it better work</p>
<p>if you make it right it will WORK!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!</p>
<p>nice this is a rip off</p>
<p>Shut up</p>
<p>this thing is the goat</p>
WHY IS IT GOING IN A CIRCLE!!!!!!!!!!!!!!!!!!!!!!!
<p>I know this is an extremely late reply, but it might help anyone else who may be having this problem with the car going in circles, you have to make sure that you have the eyelet hooks almost exactly identical to each other when screwed into the trap, otherwise it will make the axel sit at a small slant (even if you can't see it) and that will make the car go in circles. Just an idea of what your problem might be due too, try counting turns on the hooks when you are installing them </p>
<p>hahahah this is hilarious :D thanks for making me laugh</p>
<p>Nice! For Top Gear mouse fans :)</p>
<p>Elegantly simple!</p>
<p>I understand the instructions, but since I don't know the idea background, can you tell me what do you use it for?</p>
<p>My fiancee had to do this for her final. this is what we ended up with. it only has to go a linear foot to pass. we tested it, and she should pass with no problem</p>
<p> <br> <br>Absolutely <br> fantastic posting! Lots of useful information and inspiration, both of which <br> we all need!Relay appreciate your work.</p><p><a href="http://www.monacopropertylistings.com" rel="nofollow">annunci immobiliari monaco</a></p>

I really appreciate that A. you used common, easy to get materials and 2. your photos were in focus (big thank-you) and were an aid to the instructions you wrote. Thanks for the great visual tutorial. We'll be making these this summer at my Daring and Dangerous camp :)<br>
Would you be willing to explain step 10? The step where he installs the back pen? please? Thank you(:
To install the back pen, you will have predrilled (or poked (whatever) a hole and sent a thread through it. Tie a good knot in the thread to keep it from coming back out of the hole you just sent it through. Now put the pen through the two eye holes so it sits perpendicular to the wood trap in the two eye holes.<br> This is your back axle. After putting it into place I used a bit of hot glue in two single bars to keep the axle from slipping back out of the eye holes. The original creator used bottle top tabs. Mine were too big and hit the wood, not allowing it to spin freely so I decided to abandon the bottle tabs and use a line of hot glue.. After I got the back axle in place, I tied the string to the flip bar- the thing that will snap back in place once you let go it (the thing that originally was used to hold the little mouse down to the wood). <br> To make your car run after you add the wheels, hold the snap bar back and roll the back axle up so the thread is wound around the back axle. When you let the mousetrap bar go, it will fling forward and pull the back axle incredibly fast. I discovered that undoing one side of the bar so that it was actually straight on one side made it FAR less scary to use :) Check out a couple of the other mousetrap cars to see their strings attached to long poles. That is the mousetrap bar opened on one side and bent straight. So it goes from a staple shape to an &quot;L&quot; shape. It works just as well, but seems less likely to nip the user. <br>Good luck.
Thanks(: But the part that still confuses me is, what do we do with the string that comes out the other side (not the middle) of the cylinder ?
You drill a little hole. You put the string through the hole so it comes out one of the ends of the pen. You tie a big ol' know in it, or tie it to a bead or something that will keep it from coming back out of the hole. Now, you pull the string again so all the string is out of the center of the pen, but it is stuck in the pen and can't come out. Once the axle is in place, and the wheels are attached. Take the string that's dangling out and tie it to the center of the mousetrap bar. The string should be coming out of the center of the axle and attached to the center of the flip bar. The flip bar is what will pull the string and make the mousetrap car move forward when it spins the back axles, causing the wheels to move, causing the car to move :)<br> Hope this helps. Let me know if you're still unclear. I will try to explain a different way.
