Old CDs work well.
The two types of friction affecting mouse trap cars are rolling friction, which occurs when the wheels of the car are in contact with the surface, and sliding friction, which occurs between the moving parts of the car, such as the axles and the mousetrap mechanism. These frictional forces can affect the efficiency and speed of the mouse trap car.
Epoxy the wheels to the axle.
The best way to build a mouse trap car is to add four wheels to a peace of wood and add a mouse trap
Levers are a big deal when it comes to Mouse Trap Cars, levers help make the mechanical advantage and ideal mechanical advantage higher and better.
It is better to use small trap cars as the larger ones can prevent no use to trapping a mouse the small traps are much quicker to get the mouse/rats.
use a rat trap
The variables for a mouse trap car could include factors such as the weight of the vehicle, the size of the wheels, the type of propulsion system used (rubber band, mousetrap spring), and the surface friction of the wheels on the ground. Each of these variables can affect the performance and efficiency of the mouse trap car.
so the wheels will stay on straight
CD's make good wheels for a mouse trap car. They provide little friction and the large diameter will help you get the most distance.
It depends on the mouse trap that you use if you use a little cheap one they are about 3 7/8 long with width of 1 13/16 and a height of 1/4 (all in inches)
idk good luck with that...maybe bottle caps or little mini candles??? sorry that's the best i cud do
Have bigger wheels and a more powerful mouse-trap, like the really big ones that are a foot long and half a foot wide.
