Difficulty: Moderately Easy

Instructions

Things You’ll Need:

  • Mousetrap
  • Lightweight wood

  • Screws
  • Eye hooks
  • Foam board or CDs
  • Rubber material
  • Wood or metal rods
  • String

Step 1

Assemble the chassis. This platform will be the base for your mousetrap car. It will be the main piece that the wheels and any gearing mechanisms utilized in your mousetrap car design will depend on. Choose a wood that is lightweight and can withstand eye hook installation. The eye hooks will be acting as axle carriers.

Step 2

Drill hold in the platform. Drill holes in the mousetrap base. Position the mousetrap on top of the chassis. Then, screw the mousetrap to the chassis. The spring action energy from the mousetrap is the propelling force of your car.

Step 3

Construct the wheels out of lightweight materials. Foam or plastic from old CDs are good choices. Attach rubber bands, balloons or other rubber material as tire tread. The wheels should be large in relation to the axle size.

Step 4

Install the wheels and axles. You can make your axles out of wooden rods, plastic or metal rods. Make sure your axles are not bent and they are balanced. You don’t want your car to come apart at take off.

Step 5

Attach the drive string to the mousetrap car. In doing this make sure to leave the part of the string that will wrap around the drive axel loose. You want release when it reaches the end. If the string is not loose it will slow down the speed of your car.

Step 6

Lock down the trap. Wind the string tightly around the drive axel. Allow the mousetrap to release. This will set your mousetrap car in motion.

Tips & Warnings

  • Use lightweight materials to maximize coasting¬†¬†¬† distance.
  • Wind the string tightly around the axle so it cannot slip.
  • Be careful with the mousetrap.
