Step 1: Materials!
-A base- This is used to hold everything together. I used a piece of cardboard from a box getting thrown away. You could use plastic or metal or whatever!
-Two Electric DC Motors- These can be found in most anything that spins! Fans, pencil sharpeners, RC Cars. Try to make sure they're the same size, although that doesn't mean they're the same.
-Two AA 1.5V batteries- Both of these will supply three volts to the motors.
- Bottle Caps- You don't exactly have to use bottle caps. Anything round you can find to use as wheels! Bottle caps don't have the best traction, although they work on short carpet!
- Some Tooth Picks- These are used as the axle for the front wheel.
- A Two Position Switch- These have three pins. I will describe them more later.
- Some Wire- To connect the batteries to the switch to the motors.
- NOT IN THE PICTURE- 2 Popsicle sticks. These are used to attach the front wheel axle to the base of the car.
A Hot Glue Gun- Used to hold everything together. NO SOLDERING! Use the Hot Glue Gun with caution!
Hot Glue- Kind of implied but I thought I'd say it anyway!
Clippers or Scissors- Used to cut everything from the wire to the cardboard.
(Optional) Wire Clippers- Very helpful to making wire connections.
A Drill Press- (Or Something sharp to make a hole.) This is to drill the wheels to go onto the motors!
A "Holder"- Something to hold a tooth pick up so you can use both hands. This could be another person.
