Slip the loop over the end of the zip tie on the axle and wind in the opposite direction that you want the mousetrap car to travel. For a mousetrap car that will go a long distance the lever arm needs to be longer to pull more line that is wrapped around the driving axle. From these calculations it can be easily seen that the amount of force available rapidly diminishes as the length of the lever arm increases.

Tom Tremont, chief designer, describes how his studio still works as a "dedicated studio away from the mothership" and is the first to work on new platforms. He thinks that the "New Edge" look coined by Ford is only a form of vocabulary. "It's more of a crisp look, and the whole world's doing that now." Apart from the weather, another strong influence that helps the California design studios is the proximity of the entertainment industry. "The weather and different scenery nearby provides recreational pursuits all year round. The beach, the snow, they all provide inspiration," Mr. Matano says.
Where can I find more information about mousetrap cars?
This means you should understand terms such as diameter, circumference, radius, pi, rolling resistance, and rotational inertia. I have used CD’s, clear layers, and cottage cheese lids for wheels. Al currently holds the world’s record for the longest mousetrap powered car. Rober quickly learns that to have a winning mousetrap car you need a design that will deliver the smallest force over the longest distance. A mousetrap car is a toy car that can be made with household items.
How To Make A Mouse Trap Car (Simple and Easy)
It just didn’t feel strong enough though and when the teacher suggested bigger wheels I knew we had to go bigger everything. This meant finding a larger straw that would fit a dowel rod through it. I keep a rotating tray in the center of our dining table with things such as napkins, honey sticks, salt and pepper, and Milk Magic straws. How to make an easy mousetrap car for science class that travels over 6 meters, complete with video instructions too. Mousetraps work well as a mover for these types of cars because they’re cheap and versatile. They can be modified easily to do whatever you want them to provide power.
This is a DIY project that teaches you how to make a Mousetrap Car. The car is powered by a mousetrap and can be made with things you probably have in your house. Rober eventually travels to the national mouse trap car championships to see these principles in action.
Step 6: Extend the Mousetrap Arm
The direction should be the same in which you wrapped the balloon and wedge it on the pen. Point it as straight as possible and stable in connection with the trap. Do the same thing with the other end of the pen for your mouse trap car. Before sharing these instructions you should know that I’m not a science teacher.

The gearing of a mousetrap car determines the acceleration and the travel distance. Gearing can be adjusted to increase and/or decrease the pulling force, the torque, the travel distance, and the acceleration of a mousetrap powered vehicle. With all mousetrap cars the gearing is controlled by the length of the lever arm and/or the ratio of the drive axle and wheel set-up. Most record-setting long distance mousetrap vehicles are geared so that they have the smallest possible energy consumption rate or power output in order to maximize the pulling distance. Smaller power outputs produce less wasted energy and have greater efficiency. The amount of energy released by using a short lever arm or a long lever arm is the same but the length of the lever arm will determine the rate at which the energy is consumed called power output.
The great thing about the experiments presented at these events is that they... Extend the arm so its three craft sticks long and two craft sticks wide (picture 3). Like the frame, make sure to overlap the sticks by at least 0.75" or so (picture 4).

To know how much torque is being applied to a bolt a mechanics will often use a special type of wrench known as a “torque wrench” so a specified amount of torque can be applied to a bolt. Work is done when a force acting on an object causes a displacement of the object (it moves). Easy Science Fair Projects for Kids Science fairs are a long-standing tradition that provide kids with the opportunity to better understand practical concepts in fun and innovative ways.
You can make a rip in the paper towel tube so that it looks like the mousetrap is running over it or put some fake cheese on top of it for decoration. The length of this piece will depend on how much space there is on the table you want to use for your car. It should be long enough to hold a couple of mousetraps and a few inches of space between them. Hub – this the center of the wheel which attaches to the axle. The hub should hold the axle in the exact center of the wheel and the sides of the hub should be exactly 90 degrees to the axle otherwise the wheel will wobble.
When winding the string around the drive axle make sure NOT to put any slack in the string. The string should be wound tight as it winds around the drive axle or the mousetrap racer well have a jerky motion as the string unwinds. Always wind the string using the force of the mouse trap, do not help lift the lever arm during the winding process (except maybe at the start of the wind and then only just to get things going.
With all of the modifications you can do to them, there’s no end to the kinds of things you can create. There are several different ways you can make your mousetrap car. If you want to go for something more complex, there are plenty of tutorials online to give you ideas on what materials to use and how to modify your trap to get the most speed out of it. You can also check out some of the other interesting mousetrap car designs here.
Mr. Ellwood says VW is spending $500,000 on new computers, and his designers are excited about using a virtual reality room with computer-generated pictures. Certainly, nowhere have so many design studios been so far removed from the major centers of manufacturing. Students were given 3 attempts to get the farthest distance possible.
Make sure the closed arm is facing toward the small wheels as shown. Cut 3 sections of straw to fit on the body of the car like in the illustration. Be sure the straws are parallel to each other and the leading (short) edge of the cardboard. Take the 2 pieces of cardboard (about 4”x10”) and cut a rectangular notch (about 1”x2“) in the center of the short side of each piece of cardboard. Then place the two pieces of cardboard on top of each other and tape the edges together to make one double thick piece of cardboard.
You’ll need two dowels for each axle, so make sure you cut them accordingly. It is always important to understand the relationships between variables but never over exaggerate any one concept. The ideal size for an ultra big wheel on a long distance mousetrap racer seams to be somewhere between 10 and 15 inches. Understanding the physics of the mousetrap car should help in designing a more efficient operating mousetrap car.
