I have the following ingredients to make a car:
  • 1 - AA size battery
  • 1 - motor
  • 2 - big paper clips
  • 4 - small paper clips
  • 1 - 8" long 1/4" wide dowel
  • 1 - jinx wood
  • 3 - large wooden wheels
  • 2 - small wooden wheels
  • 6 - elastics (varying sizes)
  • 1 - piece of thermoplastic polymer (about 12 cm by 4 cm)
  • 4 - thumbtacks
  • 2 - pins
  • 2 - pieces of copper wire
  • 1 - marble
  • 1 - popsicle stick
  • 4 - toothpicks
  • 1 - bag (optional)
This car needs to go up 1 ramp, drop a marble into a hole, continue going up another ramp and pop a balloon at the end.

Any tips on making the car go up the ramp with the least energy possible?
Thanks in advance.
