Balsa wood, pine, or bass wood are excellent choices although balsa wood is somewhat brittle and hard to drill holes into without ripping. 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.

What materials can mousetrap cars be made of?
A mousetrap car is a model car made from simple materials that is powered by a mousetrap. A mousetrap car can be made from cardboard or balsa wood with CD's for wheels and axles of wood or brass tubing. Power to drive the wheels is provided by a mousetrap to which a wand and string is attached to the snap arm.
How do you make a mousetrap car stronger?
To adapt your mousetrap car for distance, use large, light wheels for less friction and greater inertia. For example, old CDs make great wheels to increase distance. If your car is a rear-wheel drive car, set the wheels on a narrow rear axle so the wheels turn more and travel further.
What makes a mousetrap car go faster?
A speedy mousetrap car will have smaller wheels (faster acceleration), a shorter lever arm (increased torque, but smaller travel distance), a larger axle (increased acceleration) and will generally be smaller to decrease air resistance.
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.
Why is it better to have large wheels for the drive axle on a mousetrap car?
By changing the size of the drive wheel(s) you can speed-up or slow-down your mousetrap vehicle. Larger diameter drive wheels have a greater travel distance per each turn than compared to smaller diameter drive wheels. ... For speed trap racers a smaller diameter drive wheel with a larger diameter drive axle is desired.
How long should the lever arm be on a mousetrap car for distance?
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.
What is the fastest mousetrap car?
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.
Why is my mousetrap car not going straight?
If your mousetrap car does not travel straight energy is also being wasted to over come the force of friction turning the vehicle's wheels. If a mousetrap vehicle is not traveling straight then there is one reason and one reason only: the front and rear axles are not parallel to one another!
How far did the world record mousetrap car go?
Description: The secret to Doc Fizzix's world record setting mousetrap distance racer that traveled over 182 meters was it's unique pulley system. This is the same pulley set-up that was used on Doc Fizzix's world record setting mousetrap distance car.
What is gravity vehicle?
Gravity Vehicle is an event that returned for the 2020 and 2021 competition seasons after being held in 2012 and 2013. In this event, competitors design and build a ramp and a vehicle that is powered solely by the vehicle's gravitational potential energy.
How much string do I need for a mousetrap car?
The length of the string is about 25". Therefore the string can be wrapped around the dowel 25/0.785 = About 31.8 times. So the minimum distance travelled will be the number of times the string can wrap around the dowel multiplied by the circumference of the wheels, which is 31.8 x 14.92 = 474.456", or about 39.5ft!
