The car can be made from any type of cardboard, but it is best to use corrugated cardboard because it has more rigidity and strength than regular cardboard. The car has a small mousetrap on the rear axle, which is connected to the front axle with an elastic band. The elastic band is hooked to the back of the car and pulled back by hand to set it in motion.

As the string unwinds, it causes the axle and attached wheels to rotate. The spinning wheels push the mousetrap car across the floor. Chassis – frame of the car to which the other components attach to.
Step 5: Attach the Mousetrap
By turning the drive axle the string is wound around the drive axle causing the mouse trap's spring to compress and store energy. Once the drive axle and mouse trap are released the string is pulled from the drive axle by the mouse trap and this causes the drive wheels to rotate. In a perfect universe where there was no friction this concept would not matter so much but in our real world environment friction makes a huge difference. Heat and sound are forms of friction that will eventually absorbs all the energy from your mousetrap vehicle and cause it to come to rest. Higher rates of energy output produce more heat and sound compared to smaller energy outputs.

Learning Objectives:
The faster the mousetrap vehicle moves the more air that the racer will have to push out of the way and this takes energy from the system. Design your mousetrap racer so that it can slice through the air with the least amount of resistance; design your vehicle to be aerodynamic. Try sanding and painting wood frames in order to cut down on the air resistance. Also, slow moving mousetrap vehicles will experience less friction than faster moving vehicles, design you mousetrap car to be slow moving; this can be achieved by adjusting the vehicle's gearing. Shorter lever arms have more pulling force and produce greater acceleration.

You should now have a car that looks something like the picture. Put the car on the ground and let it go and it should start rolling away from you. It will likely take some tinkering and practice to get it to roll straight and smooth.
Step 2: Attach the mousetraps
To download the Project Sheet, click on the image and then click on the download button in the lower left corner. Or, right click and open the image in a new tab, then right click and save the image. I recommend showing how to build the car step-by-step, and then use the project sheet as a reminder of the steps.

A mousetrap car is a vehicle made of wood with four wheels and a string that runs from the back axle to the front axle. When you turn the string, it causes the wheels to spin around in circles and move forward. A mousetrap car can be made from any material that can be cut into a rectangle shape. The axle should be made from something sturdy, such as a pencil or dowel rod.
Step 3: Building the axles
I have seen this work but there are some serious flaws in the application of the physics. In a perfect universe the flywheel concept would always win if we were displacing only the wheel. But we are not in a perfect universe and we are not just displacing the wheel; instead, we are displace the whole car including the mouse trap. In our real world environment we have to deal with a small but important concept called friction. A mousetrap vehicle will travel further and be more efficient the slower it moves.
Step 5: Assemble the wheels.
Make sure that they’re centered so that the wheel runs in between the space on each side of the mousetrap’s metal bar. You can use glue or hot glue for this task to hold them in place. The mousetrap car is a toy that is powered by a rubber band. The rubber band is wound around the axle of the wheels, and when it is released, it propels the car forward. As you might guess, the materials used to build mousetrap-powered cars are light out of necessity.

The Doc Fizzix’s mousetrap cars use more expensive materials such as brass axles and lever arm which is better. A mousetrap car makes for a great science project, physics classroom experiment, or a fun weekend activity. Mousetrap cars are frequently used to help students learn about mechanical advantage, distance, and gravity, with many teachers turning the experiment into a long-distance challenge.
Run it several more times and when it goes, watch it carefully to see if you notice anything that might be hampering its performance. Once you have a good idea how the car works, see if you can design another car that can travel even farther. I made these mousetrap car plans to be used with 4-H clubs where I live in New Hampshire.
Their new car with a new design and new materials traveled about 4 meters on the first try, and then 6 meters on the second (before crashing into the front door). Once you’ve tested out your car, it’s time to sit back and enjoy having built something so great. You can store it in a safe place where no one will touch it until the next time you want to take it out and play with it.
To optimize for distance, you can follow the steps we detailed above. Design a car with large rear wheels, the mousetrap as close to the front as possible, and one that has a light body. The ex-NASA Engineer is funny, goofy, but above all, really really smart. In one of his latest videos, he shows you how to make a super mousetrap powered car. The combination of hot glue, tape, and attaching the string to the underside of the arm will prevent the string from coming undone.
