How to Build a Mousetrap Car Part 5 of 5

[iNazdel]

ok so im done it finally but one wheel keeps on falling off and now i got it but it looks like it will fall off again but i guess ill see tomorow

[iNazdel]

were did u get the wire? I got string instead

[blackopszombiez420]

one problem. you can't by kites unless it's spring

[husnaan]

hey, could you tell me what to do with the string im confused

[animedictionary]

i have to use a cd for the car but would it still work??

[yellomustache4]

@Thefatguy123456 10,000 strings every year die of rape.

[CheezyDrool]

i don't see you explaining about wrapping the string around the axle, how to do it, etc. that is the heart of the mousetrap. you failed. even if you did explain it somewhere, you fail to explain it at the right moment. you should have explained it when you mentioned kite strings.

[Thefatguy123456]

can u help me plz cause how does u rape the string around it cause when i do it the string is use going therw plz help me 

[rickax123]

dont talk loser just do it

[xRawrYourMine]

Mr. Mr.! i was just wondering how far your car traveled?

cause it looks preety far to me.. but i need a measurement please and thank you :3

[Shadow082098]

Would wooden tinker toy wheels work for the back wheels?

It's about 1.5 inches long, with about half an inch width. I'm kind of short on supplies, and it's all I have...

[sarahahmed0]

About how far does the car go? Can it go close to 40 feet?

[youkluo]

CDs as wheels is better or Caps is better for max speed and displacement

[BIGfart7]

@youkluo That is where you're wrong sir. Bottle caps would be better suited for acceleration but not give you any distance. CD's are GREAT for distance, but lack on acceleration. It depends on what the teacher is asking for the assignment, but my Tried and Tested design gives a good balance of both.

[kripazznigga211]

How do you wrap the string around the axle? Are you supposed to tie the string to the axle?

[YoshiBetrayal]

If I use the same measurements you did, how long should the string be?

[heidimorton1978]

HELP ME !!!!! mine is due tomorrow, and when I release it, it jumps in the air and doesn't move forward! I don't know what's wrong. I think I should wiegh down the back wheels, but i don't know how and what to do! HELP!!!!!

[dani3lru1z]

LOL @ broken wheel. "So quick it'll destroy itself"

[lotsofgum]

Whenever i let the car go, it always has the body stuck onto the back wheel, preventing the car from moving, how can i fix this?

[BIGfart7]

@lotsofgum sounds like your wheels are too loose and rubbing on the frame. Try finding some smaller paper clips to hold the rear axle better. If that doesn't work get a longer axle to get the wheels away from the frame. AND DON'T forget to use straws as spacers otherwise the wheels will just move from left to right.

[malubabii204]

Do you need smaller wheels for the front? Or can they be the same size as the back wheels?

[dynammo12]

how far does it go?

[zelda4ever708]

Also, thanks for the videos! They really were helpful. Also, I love your voice. There's just something about it, it's awesome :P. Keep up the good work.

[Sunnyblah1]

how do u put the string on da car .i hav a project due help plz

[brighteyesxluv]

your nails are ugly clip them

[MrSmokeythedragon]

@brighteyesxluv lol he's gotten that so many times

[brighteyesxluv]

it is bad what are you saying

[Arvenpokemaster]

Hello,

The kinetic energy on my mouse trap is too powerful. When it releases the energy, it clamps so fast it enables the car to move. Did you adjust your mousetrap wire in order to make the kinetic energy go slower? If so, how did you do it?

[BIGfart7]

@Arvenpokemaster It's simple. Use a longer arm, add more weight to the drive wheels, give the drive wheels extra grip (ex. rubber bands), use bigger wheels. Any or all of those suggestions should work depending on the severity. HOPE THIS HELPS!!!

[Arvenpokemaster]

@BIGfart7 Thank you! My team got the 3rd place in Physics and I was really happy with the results!

[zelda4ever708]

@BIGfart7 So, mine does the same as Arvenpokemaster in that the arm closes too fast. It's pretty much the same length as yours (a little over a foot). Right now my wheels are rather small, they're just water bottle caps with about five of those tiny rubber bands you use for braces wrapped around each of the two back wheels. So that would be a problem? I see that you said making the wheels bigger helps, which I am planning to do, but do you know why that actually makes the arm go slower?

[emosk8erboi16]

@BIGfart7 i built this car and i was wondering how to wound the string to the back axle exactly doesnt show in the video

[BIGfart7]

@Fluffy2Fresh Like a yoyo. Just friction to the axel. NOT tied or glued.

[vsep31]

Hey how did you attach the string

[namdec100]

I don't understand how you tied the string. Is there anyway you can explain?

[bramgroenhof]

keep pressing 1 and it is driving allready and keep pressing 8 and you will here that he is hungry because he say kitka(t)

[Lopezramos123]

Wait how did u attach the string!?

[AJMacLeanWD]

cut ur nails plezz and dont make anymore cars plezz

[nachoman4793]

thank you

[dewey156]

Have you noticed that part one has the most views. That's because it sucks and people stop watching it. Those that are interested a little then watch part five (the second most watched of the five) because they do not want to listen to your long winded explanations about how to build a cheap mouse trap car that breaks. And the only reason your first video has so many views is because Mr. Lind gave us the link because he thought it would help us with our own projects. He was wrong. Burn me --__--

[Lopezramos123]

Thank u so much!! A+!!!

[BIGfart7]

@Lopezramos123 lol, Glad to help!

[zxc56km6]

the whole 7th grade is making these...

[SillyDuck2]

is that a mousetrap or a rat trap? cuz that trap looks kinda big D:

[lavonnejackson]

i hate this project

[YourSoxRox]

@lavonnejackson aint no skyrim doe

[superspy246128]

How did you make it so fast. I tried using rubber bands, light weight wood as base and plastic wheels but the mouse trap goes very slow. Is it because of the mouse trap itself that isnt powerful enough or did i do something wrong?

[nerministhebest]

I dont understand what you did with the string.

& Also, what is the purpose of the coat hanger?

& Would you be able to give me some advice on using the same technique, but using CD's as wheels, rather than juice caps.

Please reply asap! It will mean alot! Thank you!

[smashleigh2575]

what can i substitute for rubber bands?

[TAGHERO1010]

ur right it actually runs FAST!!!! i have a month to build this i'm so lazy......

[pkerf2p49955]

can you use lego wheels for the back and front?

[evilnegi]

its so quick it will destroy it self hahahah

[fadya97]

Thank u so much ! U saved my life!!!!!

[skaterboy10992]

I used pinewood derby car wheels instead of juice caps and it worked perfectly thanks man oh and tip on the threading use a zip tie on the axel trim off the excess from the zip tie make a small loop and hook it on the zip tie then pull your car back like an old toy I found the solution on another how to video

[ceci13th]

how do put the wire on the mousetrap??????

[Gogeta37]

To everybody wondering how to "load" the mousetrap car and how to attach the string...he explains it in the " Ultimate Mouse Trap Car Instructions" video

[Novastarism]

can we use tape to keep the string and back axel together? answer asap plz and thx

[mylove1398]

thank you soooo much!u saved my life!!

[BahhhRahhh]

How did you attach the string to the coat hanger? u didnt explain..

[TimeStopper900]

You sir have saved me from failing :D

[IxHazxRandomness]

Dude, attaching my arm was the most annoying part of the whole thing. Using duct tape definetly proved to be a challenge.

[xKnightx3]

For the people who need to tie the string,

i used some of the blue tape that you use when you paint to tape the end of the string to the axle. Then when i wind the string, it should wind on top of the tape. When i did that, my car worked. :D

[xKnightx3]

how did you tie your sting?

[pphreshs]

thanks a lot this is a guaranteed A :)

[rayz0r13]

I agree with MaryDMill90k, I love this tutorial, you've done a great job in explaining almost everything, but I think you kinda forgot to teach us how you wound the kite string on the rear axle. A quick explanation would be bloody great.

Cheers

[Lilcesar203]

yea let it dry nice and hard

thats what she said

[PATTH3RAT]

how did you wind the string on the axle in the back?

[xiaphus9]

Hey is this effective for going up at 30 degree wooden ramp?

[kuzzkoacademy]

no dislikes on any of the mouse trap car vids great work =D

[kwynn7]

yes!!! NOW I WILL ACE MY TECH PROJECT!!!!! WOOT!

[augustlatino]

thanks man! now I can finally do my physics project!! :D

[HelloMan93]

Wait, so how DID you wind up the string to the axle?

I already had ideas for a car but i never had the idea of how it can be wound up =/

[Hyde4ever]

I did every part you made, I tried winding the string(had to use thread but I braided it) but it made my car do a 360 instead, now i put 2 double a batteries on it and upbraided the thread, now the thread is getting caught and wont unwind the axle all the way, so then i assumed the thread was to long and cut the long rod in half and shortened the thread, its still getting caught and not unwinding, dunno what to do...

[kryonikkid]

would bottle caps work good like water bottle caps

[wally1160]

quick response please.... i have still got the problem of the mouse trap doing a flip can oyu please tell me if there is a good way to stop it flipping. how do you put the string around the axle properly i don't think i put it on right

[AriesApRiL95]

How do you wind up the string? And how do you attach it to the mousetrap car??

[thumper51000]

7:28 <-- thats what she said?

[lavenderpinkiwii246]

thanx for making this vid it did help

[respinoza214]

how did you wind it up?

[darkmoon005]

I am required to put two rolls of 50 pennies on the mouse trap. Where should i put them (front, back, middle??), and will it still go about 4 or 5 meters? Quick response please!?

[Roflandherewegoagain]

THANKS ALOT ,great vid, and i haven't got any words for this gudie. I can just say great work :)

[drewstew333]

whats with your user name , are you still 11

[kiliksapprentice339]

What did you use to keep your string attached to the back axel so you could wind the string up around it without it slipping and coming undone, and so by the time the string completely unraveled from the axel, it won't tighten and accelerate the car backwards?

[BIGfart7]

@kiliksapprentice339 friction

[MaryDMill90k]

@BIGfart7 um no, it not friction. you need more detail on how to get the string to stay on the back axle because im sitting staring at my mouse trap car with everything done exept for the last freakin step, which is the one you forgot to explain. ( how to keep the string on the back axle )

It would be awesome if you could tell me how and help me out man

[Folcard10]

this video sucks ass

[Aviationist11]

Nice Vid dude. You are a mature man and even thought you broke a wheel you didnt curse. Thanky you for making a clean and good vid.

[PhantomWarlock]

to make it go 4meters would i just adjust the length of the string and run trials?

[xxxd0ughb0yxxx]

Im going to attempt to build this now bc its due tomorrow, but i don't understand the last step of you attaching the string to the arm, may you quickly explain?

[TiaPooh101]

what type of wire did you use?

[lilahsch]

Thank you bigfart7 so much!!!!!!!!! You've really saved my butt! My car works perfictly

you are the best!!!!!

[basketball31princess]

how do you tie the string??? we really couldnt see it very well in the video and i have no idea how to do it..?

[WinnieKongg]

How come ur wheels don't wobble

And can I make this a bigger version?? And still have a pretty good result?

[BIGfart7]

@WinnieKongg If you make the car bigger, the mousetrap will be pulling more weight. Giving it worse accel. and distance.

[Moss81pats81]

how do u get the string on

[airventschinatown]

How can I make it reversable? Will I need to make it wider? I have a project and it has to go 7 meters foward then backward.

[SiD3sH0w510]

I having trouble getting mine to go, I just having a problem winding up the string and then when i let it go the mousetrap goes, and there's no tension between the string and the axle

[Fashionwonderwomen]

Thank You for the video but I am still really confused, what do i do with the string, does it not go into the wheels?

[XxcoolXx02]

thanks :)

[wenstaphonie]

dude! u should have told us what size trap to get! apprently,urs is the small type......i got the big type....and i cant "strip" it down,is that ok,pls reply in a day or else im scrwd

[BIGfart7]

it's called a "mousetrap car" for a reasion. you bought a rat trap

[Bored4NOreason]

Thanks so much! I just have one quick question though. How much of a difference do the rubberbands make? We're making a mouse trap car for school and the requirments say we can't use any rubberbands or elastics.

[BIGfart7]

ask if you can use just 2 rubberbands as extra grip for the rear wheels. if not then i'm not sure what to do.

[megafart61]

thanx so much! best mark ill ever get. xp

[richardtherichard]

*thank for (typo in previous comment)

[richardtherichard]

thanks of the videos. it gave me an A or B+ at least.

[BIGfart7]

for the front, but you need bigger driving wheels or the car will hardly move

[tilldeathcomes12]

hey how do u get the car to go faster and make it go straight

[aquademon6]

thank you man

gave me a good guide to build one

[eddie408209]

thx a lot man u saved my grade for physics :D

[aAverageGuy]

how do u tie the string to the coat hanger and the axle?

[BIGfart7]
