How do you make a straight line mousetrap car?
Using a small round file, remove some of the material on the back side of the axle hole on the right front in order to bring the axle hole closer to the rear and get the front axle pointed straight. Only remove small amounts of material and test run the mousetrap vehicle until the racer eventually travels straight.
How do you make a rodent car for free?

Is wood or cardboard better for mousetrap car?

Other materials can also be used for making a light weight strong and stiff frame. These include Styrofoam, corrugated cardboard, plastics, aluminum and brass tubing.
How long should the arm be on a mousetrap car?
For maximum speed, position the mousetrap 2 1/4 inches from the drive axle and cut the lever arm to a length of 4 1/4 inches. The lever arm can be cut using a dremel tool or by using a fine tooth hobby saw. The lever arm should always be “just” long enough to reach the drive axle or performance will be compromised.
How do you make a mousetrap car stop at a certain distance?
Setting the braking system is simple and easy: just place the vehicle at the finish line with the wing nut in the lock position, roll the vehicle back to the start line and the wing nut is set to the exact starting position.
How big should the wheels be on a mousetrap car?
The ideal size for an ultra big wheel on a long distance mousetrap racer seams to be somewhere between 10 and 15 inches. And the ideal size for a drive wheel on a speed-trap racer seams to be between 2 and 3 inches but no more than 4 inches.
Does Irish Spring soap keep mice away?
Many people errantly assume that Irish Spring soap will keep repelling mice. However, there’s practically no evidence to support this claim.
Will dryer sheets keep mice out of a car?
Do Dryer Sheets Keep Mice Out? Don’t expect your box of Bounce to work any pest-control miracles. Dryer sheets don’t deter mice.
Why are CDs good for mousetrap cars?
Why do so many mousetrap cars use CD/DVD for wheels? Because CDs and DVDs are some of the best wheels you will ever find for building a long distance mousetrap powered vehicle. CD/DVD wheels can slice through the air with very little air resistance and they have very little rotational inertia.
What do you put in a mousetrap car arm?
In most cases brass tubing and brass brazing rods make excellent lever arms because of their high-strength and light-weight. Wood can also make for a very strong and light-weight lever arm if it is used properly (see making a super long lever arm).

Should a mousetrap car be heavy or light?

What kind of string is best for a mousetrap car?
The string has to be strong enough to handle the pulling force but flexible and thin enough to wind tightly around the drive axle. We recommend using a Kevlar based fishing line because its high strength. You should stay away from nylon fishing line and dental floss, these do not work well with mousetrap racers.
What is the fastest mousetrap car design?
The Speed-Trap Racer is the fastest mousetrap powered racer anywhere and was designed after Doc Fizzix’s own record-setting mousetrap racer that traveled 5 meters in 1.2 seconds.
How do you make a super fast mouse trap car?
By changing the size of the drive wheel(s) you can speed-up or slow-down your mousetrap vehicle. Larger drive wheels have a greater travel distance per each turn compared to smaller drive wheel. As the size of the drive wheel increase the torque required to start a wheel turning also increase.
What is the best amount of wheels for a mousetrap car?
So what is better, three wheels or four wheels? The answer depends on the contest, if we are to build a super fast accelerating speed-trap racer then over coming rotational inertia is one of the main objectives therefor three wheels will always do better than four wheels when it comes to performance.
What scent will keep mice away?
You can use certain scents (ammonia, eucalyptus, chili oil or powder, lavender, mint) to keep mice at bay but this definitely won’t work if mice are already inside your property. We strongly recommend getting the help of a professional pest exterminator to save yourself time, money and unnecessary stress.
Are big wheels better for a mousetrap car?
Wheels and Axles Larger drive wheels will have a greater travel distance per each turn compared to smaller drive wheel. It would make sense to use a super huge drive wheel so for each turn of this massive drive wheel the mousetrap vehicle will travel an incredible distance.
How do you make a mousetrap car go forward and backwards?
To make a reversing mousetrap car go forward and then come back you will need to know how to “back-wind” the string. Back-winding the string it a technique where you first wind the string around the axle in one direction and then rewind the string in the opposite direction.
