What is the fastest mousetrap car design?
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.
Should a mousetrap car be heavy or light?
Lighter mousetrap vehicles will require less energy at the start and can use longer lever arms for more pulling distance. Always use lightweight components when building a mousetrap vehicle. bonus tip: lightweight mousetrap vehicles require less pulling force off the start.
How long should a mousetrap car string be?
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!
How do you make a mousetrap car go forward and backwards?
To make a reversing mousetrap car go forward and then come back you will need to know how to “back-wind” the string. Back-winding the string it a technique where you first wind the string around the axle in one direction and then rewind the string in the opposite direction.
Is weight important in a mousetrap car?
The greater your mousetrap vehicle weighs, the shorter the distance it will cover and the speed it will travel. This consequence is due to the limited energy within the mousetrap.
Is there a life size LEGO car?
The ’90s superstar is one of the most iconic models that have ever rolled out of Maranello, so it’s just fitting that it finally gets its own life-size model made out of hundreds of thousands of Lego bricks.

How do you make homemade traps?
Dig a hole in the ground that conforms to the size of the nuisance animal, making it deep enough so the animal theoretically can’t climb out. Cover the hole with brush to disguise it. Place the appropriate bait for the animal on top of the brush. Wait for the animal to take the bait and fall into the hole.
Why is my mousetrap car not moving?
If you place your mousetrap vehicle on the ground and the vehicle does not move, or it does not accelerate as quickly as needed, then you can do one of two things, you can shorten the length of the lever arm and reposition the mouse trap closer to the drive axle or you can build up the drive axle with tape (see how to …

Max Length – 45 cm. Max Width – 20 cm. Height – 20 cm. Min ground clearance – 4 cm.
How do you make a LEGO car go faster?
Make it heavy! Make sure that your tires don’t rub against the side of your car! Larger LEGO® wheels are generally faster than smaller LEGO® wheels. If you can, use Technic axles and wheels instead of the clip-on wheels, they are faster!
How do you make a mousetrap car move?
The most basic design for propelling a mousetrap racers is to tie one end of a string to a mouse trap’s snapper arm and then attach the other end of the string to a drive axle. By turning the drive axle the string is wound around the drive axle causing the mouse trap’s spring to compress and store energy.
How do you make a rodent car for free?

Are big wheels better for a mousetrap car?
Wheels and Axles Larger drive wheels will have a greater travel distance per each turn compared to smaller drive wheel. It would make sense to use a super huge drive wheel so for each turn of this massive drive wheel the mousetrap vehicle will travel an incredible distance.
Which LEGO car is best?

What is the best amount of wheels for a mousetrap car?
So what is better, three wheels or four wheels? The answer depends on the contest, if we are to build a super fast accelerating speed-trap racer then over coming rotational inertia is one of the main objectives therefor three wheels will always do better than four wheels when it comes to performance.
Can you build your own electric car?
