Hybrid vehicles during the 1900s, propeller cars are certainly one of the best innovations that were created during the early years. It can move as fast as 85 miles per hour but as the innovation progresses, present propeller cars can now travel as fast as 170 miles per hour.
The motor of a propeller car does not power the wheels but the “propeller” itself. Because of such simple structure, many believed that it can lessen the amount of fuel needed to make the vehicle work.
So let us start building our simple propeller car for this experiment so that you will understand how it really works.
Materials:
1 2×10” piece of flat wood (you can use an old ruler made of wood)
2 Straws
4 Caps from plastic water bottles
1 motor
Small piece of wooden block
1 plastic playing card
1 paper clip
2 brass tacks
9V Battery
9V Battery Snap with wire
Drill
2 Skewers
Glue gun
Glue stick
1 red wire
1 blue wire
1 Connection wire
Rubber band
Procedure:
Insert 1 skewer on each straw. The skewers must be longer than the straws. Using the glue gun, stick the 4 caps on the middle of each skewer end. These will be the wheels.
Drill 4 holes on your flat wood, about 1.5 to 2 inches apart. Loop the paper clip on one of your brass stacks. This will serve as your switch when you attach the other end to the second brass stack.
Attach the 2 brass stacks on the middle holes and secure it around the wood.
Cut about two-thirds of your playing card and attach it on the tip of your motor where it rotates. It will serve as the propeller. Attach the motor on top of the wooden block using your glue.
Attach the wooden block about 3 inches far from the last hole using a glue stick. Place the battery snap in front of the flat wood and secure it using a rubber band. Insert one of the wires of the battery snap inside the first hole (nearest to the snap) and attach it on the clip of the brass stack which has no paper clip. Insert the second wire inside the first hole once again and out on the fourth hole (the one near the motor) so that it will be on the front once again. Attach it on top of the motor. You can either solder or twist it on the inside. Attach your 9V battery on the battery snap.
Get your wheels and attach each of them on each end of the flat wood. Look for a clear area and fasten the paper clip on the other brass stack so that electricity will travel from the battery to the motor. The propeller must work.
