One of my sons friends stayed over yesterday and mentioned in passing he'd been assigned to make a mouse trap car for school. I thought about how I had lots of fun making those way back and decided to make one out of scraps off my desk and document it. It's far from the best one ever and unlikely to win any awards, but it does work.

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.
<p>how long and how wide dose the wood need to be</p>
<p>how long is the string</p>
<p>Fisheadope</p><p>Why don't you make it 4 wheel drive, when the bar of the first m/trap reaches it's travel end, it trips the 2nd m/trap and drives the front wheels , you would need to up the gearing to suit !</p>
Tape is better than Balloons for this kind of Mousetrap Car.
<p>What was the maximum distance traveled?</p>
<p>I still haven't got round to making this, can't wait to start!</p>
<p>im making one for science class and it better work</p>
<p>this is really cool</p>
<p>i gotta make this for school</p>
<p>me too</p>
<p> Same!!! Lmao!</p>
<p>same lmao </p>
<p>Does it go 5 meters?</p>
<p>I know this thread is really old...however if anyone is avail to answer~<br>Why does the front axel have brace's on it (the can tabs) but not the back axel?</p>
<p>To keep the front wheels straight and aligned</p><p>I believe that if they weren't there the car would turn a little to the left or right</p>
<p>also~ if you use balloons (or rubber bands) to fit the disks~ would it be beneficial to hot glue them in place so they don't slide? </p>
<p>Thank you for the advise</p>
<p>How far does it go?</p><p>More than 5 meters?</p>
<p>which size mousetrap</p>
<p>This is just so cool! I have to make this for the school! thanks for sharing! It's so exciting to watch the video..... (minus the ouch part!)</p>
<p>is there anything I can use instead of eyehooks</p>
<p>Virally anything really. Screws/wire or some bent metal perhaps. I'd probably stick to screwing whatever onto it rather than glue or tape - it gets yanked around quite a bit when it moves. Any wood screw works tho - find some broken thing and raid. </p>
<p>i made it it mad 6 times before falling apart</p>
<p>I made it but it lasted 5 runs before collapsing</p>
<p>make it come back and I'll be impressed.</p>
<p>wow that is good I'm 19 years old and mine would have never been that good??????????</p>
<p>Cool, I will use this for my science assignment since I otherwise would have no idea how to build one. Thanks, hopefully I build it right XD</p>
<p>next step AI</p>
<p>can any help me with step 8 my mind is so out of it i don't know what to do</p>
i tried to make this &amp; for some reason the car will not move. any advice?
<p>I made one and it works great. I honestly thought that it wouldn't work but it did.</p>
<p>hope this works</p>
<p>About how far does this go? My sience rubric requires it to go at least 12 ft..</p>
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>What website/book did you use???</p>
<p>i made it and it was so fun</p>
<p>Hey, will this car go 5 metres? I have to make one for my Physics class, and it has to go 5 metres and not weigh more than 3/4 kg.</p>
<p>How can you make the wheels more secure without using the balloons?</p>
<p>mug awesome reids not </p>
<p>mug awesome reids not </p>
<p>mug awesome reids not </p>
<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>
