Step 1: Make the Car Body

• Take one plastic bottle and remove any labels.

• Cut out a rectangular window

This will be your car chassis.

NEXT

Step 2: Prepare the Axles

• Cut two equal pieces of straw (about 5cm each) and glue/tape them horizontally under the bottle, one near the front, one near the back.

• Slide BBQ sticks through the straws, these will be your axles.

NEXT

Step 3: Make the Wheels

• Poke a hole through the center of each bottle cap using a nail or heated metal skewer.

• Insert a cap onto each end of the BBQ stick and secure with glue or tape.

• Test roll your car, it should move freely!

Step 4: Add the Motor

• Attach the DC motor to the side or top of the bottle using glue.

• Attach a small wheel or pulley to the motor shaft (or use a piece of pen cap or bottle cap).

• Loop the rubber band around the motor pulley and the rear axle (wrap it tight so it grips!).

Step 5: Power It Up

• Connect the battery holder to the motor using wires.

• Secure the battery holder on top or inside the bottle.

• Insert the AA battery.

Step 6: Test Drive

• Turn on the switch or connect the wires.

• The motor should spin, turning the axle and making your car move forward!
