How do I make my mousetrap car go further?
Mousetrap cars will go farther if the spring has more distance from the back wheels. Create traction on the wheels. Add rubber bands, or tape around the wheels to give them better traction. The better the wheels can grip the floor, the farther the mousetrap car will go.
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 kind of string do you use 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 materials do you need to build a mousetrap car?
What You Need:
- Wooden snap-back mousetrap.
- Duct tape.
- 4 eye hooks.
- Wooden dowel that fits inside the eye hooks.
- Heavy cardboard.
- Large and small rubber bands.
- Foam board (usually found at a craft store)
What can I use for wheels on a mousetrap car?
As you might guess, the materials used to build mousetrap-powered cars are light out of necessity. Foamcore board or balsa wood are often used for the body. The wheels can be off-the-shelf radio-controlled car wheels, but many builders use blank CDs or DVDs because their thin edges reduce friction.
How long should a mouse trap car be?
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.
What can you use for wheels on a mousetrap car?
How is the string connected to the axle on a mousetrap car?
A basic mousetrap car is powered by attaching a string to the “snap” lever on the trap, looping the other end to a small hook on the axle, winding the string around the axle of the car pulling back on the lever and arming it.
What kind of string is best for a mousetrap car?
What is needed to build a mouse trap car?
Materials Needed for a Mousetrap Car. There are several materials needed to build a basic mousetrap car. These items should be available at your local hardware store. You need a wooden mousetrap, two rubber bands, metal rods, eye screws, plywood, a drill, a small handsaw, a scale, a ruler, a vice or someone to hold the project steady, and wood glue.
What do levers have to do with mouse trap cars?
Mousetrap cars are powered by the spring of the mousetrap. When the mousetrap snaps back, the lever causes a release of energy . The lever is attached to a string that is wound around the back axle of the car. Therefore, when the lever snaps with the mousetrap, the string unwinds, which spins the axle and makes the car move .
What are the instructions for mouse trap?
Mouse Trap Instructions Release the arm bar from the staple. Move the arm bar to the back of the trap so it hangs over the back of the trap. Apply a small amount of high-protein bait, such as peanut butter, hazelnut spread or bacon to the yellow plastic pedal on the trap as shown.
How do Mousetrap powered cars work?
The mousetrap powered car works by changing the kinetic energy (of a loaded mousetrap) into kinetic energy (when the trap springs). The jaw snapping shut pulls the string, which makes the axles turn, which spins the tires-propelling the car forward.
