Everyone loves toys but it will be very exciting to build one's own toy. For instance, a mouse trap car. It is mostly used in science projects for education purposes apart from car competitions. However, it is not very difficult to setup one's own. Actually with the correct materials and tools, it will be easy to have one ready and running down a hallway in just a matter of few hours. It can be tried today by just following some simple steps on how to build a mouse trap car explained below.

First, a new mouse trap is needed and the wire that holds the opening of the mouse trap has to be looked for. Extra care has to be taken when meddling with the trap. Then, pliers have to be used for removing the wire and the bait holder from the trap. Two eye screws are needed for creating holes at the end of the mouse trap. It has to be noted that these holes should be made at a distance of 8mm from the edge before they are screwed right into the holes. Now, making the wheels of the car has to be focused. For making the shape of the wheels, four circles have to be drawn measuring 75mm each on the plywood with the use of a compass. Actually the size of the circle can vary based on preference.

When the circles have been cut out using a saw, it has to be ensured that the wheels are made smooth by using file. Now, two metal rods have to be held where they have to be cut into equal length and then proceed with using a file for making their edges smooth. A rod is needed first where a cut has to be made halfway into it. Then, the wire of the trap has to be place which was removed earlier on into the slot that is created. The wire has to be secured on the slot of the axle with some glue and it has to left to dry for one night. Next, the rod has to be fixed on the end of the trap where the eye screws have been put in place in the earlier phase. Same has to be done with the other rod also. Washers have to be used for holding the axles together. A hole has to be drilled in each ready cut wheel in the center. Now, slide all of the four wheels on each side of the rods.

Finally for the car engine, a string is needed to tie it to the center of the jaws of the mouse trap. A loop has to be made for the end for reaching to the rear axle of the trap. Two rubber bands have to be glued together around the back of the wheels.

Now the mouse trap car is finally ready for a race. For making further improvements or enhancements on the car, it is recommended to experiment with various wheel sizes and additional features for a more dynamic design. The car can be displayed down the race track by using marker or colorful paints on the car wheels.
