So I have to build a self propelled car of some sort that moves around in a circle that is one meter in diameter, the track is thirty centimeters out side of that. I thought about use a magnetic rail system, but its too expensive for me at the moment. Any ideas how to build a vehicle like this would be appreciated. Thanks
Forgot to add that I can not touch this vehicle after setting it in motion and that it needs to have a more complex propulsion system than a simple rubber band or mouse trap.
Answer
how long does the power to the vehicle need to last?
It doesn't get too much more simple than taking a mouse trap (or rat trap for more power), attaching a long piece of wood to act as a long lever to the bar of the trap, and then wrapping a rubber band around the rear axle of the car.
simple and very cheap!
Google "mouse trap car" if you want pictures, kids do this all the time in science and engineering programs.
EDIT:
is the track outdoors? You could build a simple solar panel to run the car.
If the track is inside, is a gear and spring system (like on the pull-back-and-release toy cars) an option? Or is that still too simple?
What about air-propelled or a miniature steam engine?

What about a small electric motor, running off a battery?
A chemical reaction (vinegar/baking soda) can power a toy car for a good distance.

Why do some women have kids just to dump them in daycare?
They ca
Now that I have your attention, I have a legit question. Why do people have children just to dump the child off in school once they turn 5 years old? We have these people making judgements about daycare, yet isn't school the same thing? Kids are in school for about the same amount of time. Just think we they get older and are involved in sports/band/choir/etc. How terrible that these children can't spend every second of everyday with their parents.
(note the sarcasm)
Kimberly, see where Isaid note the sarcasm?//I posted this because Ise daycae-bashing question every day. MY ids aren't in daycare but I know parents who have to put their kids in daycare. I've seen people say on here "Oh, those poor childrne have to be away from mommy 8 hours out of the day." Now remind me how many hours a child is in school? Isn't it 7 or 8. Then when they start with sports and then an after school job when they turn 15 or 16, that's even less time with mommy and daddy. Why don't these same people complain about this even though not sending your kid to school is illegal?
Answer
Like Ellie said, thank goodness you were being sarcastic, cause I was very tempted to give you a tongue lashing too! :)
I don't understand why either group, (the SAHM's or the working moms), feel it necessary to insult and put down others for the choice they have made. The comment that people have made, "Why have kids if you are going to have daycares raise the?" is just really rediculous! So basically, without just outright saying it, these people are saying that unless someone is financially able to stay at home with their children and not use a daycare or a private babysitter, then they don't deserve to be a parent. That is very judgemental and just plain hateful. Not every woman has the luxery of falling in love and marrying a man who makes $35-60,000 a year. I married one who only makes about $25,000 and brings home alot less after he pays child support on his children from his ex-wife and insurance premiums on all the kids. I don't think the fact that I didn't marry someone who made alot of money, means that I dont deserve to have children.
What about a woman who is widowed? My best friend was widowed with 2 young children, and had no choice but to work to support her kids. So I guess according to some of these women, she didn't deserve to have the kids, because she ended up having to put them in daycare. Point is, no woman, even these ones that are so freely judgeing working moms, know how their life will turn out and what might happen to them.
I don't know any woman who enjoys dropping her kids off at a daycare in the mornings, I certainly don't. But my husband and I live in an older house, and have had alot of things break, like our hot water heater, pipes, leaking roof. We have not had the money to repair these things outright, so we have had to charge them on a credit card. The motor on my car blew up and it cost over $2,000 to fix it, so again that went on the credit card. I was a SAHM for 18 months, and any unexpected large expense that came up, went on that cerdit card. So, I will be trying to pay all that off for years now. But it was either do that, or go without hot water, or no water, or have no vehicle. Which would have ended up hurting my kids more than me. So I did go back to work, and I do have to take my daughter to a babysitter during the day.
I do not live an extravagant life. I don't go shopping every month, I don't have a Coach purse, we don't have 4 wheelers or motor bikes, we don't go on vacations, we don't eat out every week, I don't buy new clothes for myself on even a monthly basis. If I have an extra money, from working over time or getting a bonus at work, I spend it on my husband or kids, not on myself. I took some extra money I had about 4 years ago, and bought my husband one of those $65.00 do-it-yourself outdoor pond kits, and some cheap 25 cent goldfish to go in it, and helped him make it, for fathers day, and I have had women on here tell me that was an expensive, frivolus expense and that is probably the reason I have to work, cause I am wasting money. I never knew buying my husband a fathers day gift would be considered "wasting money"!
If a mom chooses to work, because she does not want to stay at home at her childrens expense, then I don't think that makes her selfish at all. In fact I think it makes her a loving, wonderful mom. If choosing to stay at home, means that you and your husband have to stretch and skrimp so much with his paycheck, that you find yourself telling your kids "No, you can't have that, we can't afford it." or not taking them out to eat or to the movies occasionally (cause you have to pay the electric bill), not being able to buy them new clothes or toys occasionally (and I don't mean the cheap $2.00 toys at the Dollar Store that fall apart within 3 days) or you just simply have no extra money for "extras", then I do think that the mom staying at home ends up affecting the kids in a not so good way. Sure, they have mommy at home with them all the time, but if they never get the "little extras" that I know most kids would like to have and enjoy, then I think to alot of kids that is not worth it. I have seen stay at home moms, who have to skrimp and save so much that they can't even buy their kid Christmas presents or a Halloween costume. So, how is that fair to the kid?
I realize that not all daycares are great, but their are alot of women who do daycare out of their home. I found a wonderful older lady who watches kids out of her home. She is very inexpensive compaired to dayca
