how do you attach the car part with the mouse trap to the axle? How do I make the wheels turn with a string?

you're supposed to wrap the string around the axle tight enough so that when the trap sets off it will pull the string, causing the axle to rotate, which in turn will spin the wheel\n\nthe key to winning: USE GEARS OR PULLEYS.

tie a string to the tooth and on the other end of the string tie it to a car and have someone takeoff

try taking the mouse apart and clean the wheels in it

The way to do this is to first work out the acceleration required to turn the car round the curve.\nFrom there it is a simple matter of working out what angle the road needs to be at so that gravity will provide that acceleration.

We would build a jumbo cart that could hold many kids and put lawnmower wheels on it or bigger wheels if we could find it and a bunch of us kids would hop on and some would take turns pushing it down the hill....it had a steering wheel of course -taken from a scrap car...and reflectors for that matter. Later on we learned how to put lights on it hooked up to a car battery. We built tree houses and my dad helped us run the wires to have electricity (we didn't have water though)lol We played a lot of ball games and if we didn't have a ball handy we would just use a 500ml juice box rinsed out and squashed.... condensed milk cans attached to a string made for a nice racket if you walked it down a bumpy rocky unpaved street...steel drums made for good 'pan' drums and I can play quite nicely on a good set of pots and pans thank you very much :-) I'm a girl but I was the biggest tomboy ever...I always thought guy things were more fun and toy trucks etc were pretty easy to build. (I designed and made a working car engine for a full size car at 16) Today kids are stuck in front of video games and don't use their imagination or get physical exercise nearly as much as we did. I don't know what intellivision is and I've heard of Atari but never played it-granted I live in a different country from you and also grew up in another country where there was no Atari etc.

Probably the simpliest way I can think of is just to strap the balloon to a set of wheels and position it so that the opening is point in the opposite direction you want the car to move.  When the balloon is released, the air can escape out the hole and propell the car forward.

The easiest mousetrap car race to design a mousetrap car for is the speed race. Since you don't know what kind of matearails to use and the size of the wheels to use, I will give you some pointers. First for speed you need something lightwieght, like plywood. The car itself has to be low to the ground. Though you  have to leave enough clearance for the wheels to fit. You should use DVDs or old CDs.

When I did this, I used CD's. One problem you may have, depending on how quickly your car puts the power down, is the lack of friction.  Overall, it seemed to work well, just make sure you have the wheels properly aligned.

hold down the control key and rotate the mouse wheel.

1) Find the spare tire, jack and tire iron.\n\n2) Make sure that the car is in gear (or in "park" if the car is an automatic) and the emergency brake is set. The car should be parked on a flat piece of pavement.\n \n3) Remove the flat tire:\n- use the tire iron (the L-shaped bar that fits over the wheel lugs) to loosen each wheel lug. Once you have accomplished this, move the jack underneath the car. \n- raise the car with the jack until the flat tire is completely raised off the ground. Once this is done, remove the wheel lugs completely.\n\n4) Install the spare:\n-  position the spare tire over the wheel studs. This is the most physically challenging part of the whole process. You'll have to hold up the tire and try to line up the holes in the wheel with the protruding wheel studs located on the brake hub.\n- after you have the spare tire hanging on the wheel studs, screw each of the wheel lugs back on.\n-  once the spare tire is on, carefully lower the jack. Pull the jack away from the vehicle.\n- the final step is to tighten down the lugs completely.\n\n5) Put the flat tire in the space where the spare tire was and put the jack and tire iron back in the car.\n\ncheck out the detail and "How To" video at source.

Use the java.awt.Robot class mouseMove() method.  You can actually move the mouse, make it click, etc.  This is invaluable for automated testing, self-running demonstrations, etc.  \n\nhttp://java.sun.com/j2se/1.5.0/docs/api/java/awt/Robot.html

With the lighter in your hand, and with the little red button closest to you, put your thumb on top of the wheel, and (as quickly as you can), firmly spin the wheel toward you so that you end up with your thumb pushing the red button.\n\nThe wheel is flint.\n\nThe red button allows the gas to come out.\n\nThe spark from the flint lights the gas.\n\nYou'll want to keep the red button pressed down for as long as you need the flame.

jus click on it and hold it down..\nand drag it to where you want.

The simplest explanation I know is in terms of the instant center.  We all think of a wheel as rotating about its axis.  That is true, relative to the tricycle frame.  However, relative to the ground, the axle moves forward.  The point where the tire touches the ground is stationary.  It does not move with respect to the ground.  An instant later, another part of the tire is touching the ground and again, for an instant, that point on the tire is stationary.  \n\nOn any rotating body, the spot that does not move (it may rotatebut not translate) is the center.  At any instant, the part of the tire touching the ground is not moving and is, by definition, the instant center.  The wheel is rotating about this instant center.  SInce the pedal is above the instant center, your forward horizontal force rotates the wheel forward.\n\nYou can prove this all to yourself by trying a few things with the string on the pedal.  Instead of pulling horizontally, raise the angle of the string.  When the line of action of the string passes through the contact point between the tire and the road, you will find that pulling on the string will not rotate the wheel.  If you pull hard enough the trike will move but the front wheel just skids.  Since the line of action of the applied force is passing through the center of rotation, there is no torque to spin the wheel.\n\nRaise the string higher and the trike will roll backwards because the force is acting on the other side of the center creating a torque in the opposite direction causing the wheel to turn the other way.   \n\nIf you don't have a trike handy, you can do this with a spool and a string.  Just wrap the string sround the spool with the end coming off the bottom of the spool.

1.  Hurl it spinning into space.  The vehicle will spin around its center of gravity, and its center of gravity will travel in a straight line.\n\n2.  Balance it on a see-saw three ways: upright, on its side, and on one end.  Each balance will define a middle plane that cuts through the vehicle.  The intersection of the three planes is the center of gravity.

Get two tires that still have the rims in them.  Get two pieces of 2" metal pipe about 8' long.  Have someone weld the pipe to the center of the wheel.  (Make sure you stick the pipe through until it just touches the ground).  Then drill holes through the pipe and insert threaded bolts that have a ring shaped end and secure with lock washer and nut.  Where you put these will depend on who is playing.  For kids put net down closer to ground.  Use guy-wires to ground if to unstable.  SERVICE!

Throw a wrench into there clog wheels and do something different sometimes and see what happens
