Step 1: Cut a straw into two pieces three inches long. Step 2: Then glue the straws perpendicular to the bottle around four inches apart from each other to act as axels for wheels. Step 3: Puncture a hole near the bottle opening. Step 4: Place second straw through hole and out spout for propulsion.

How does a water bottle car work?
The Holes in the Bottle
A large straw is placed through the bottle and students blow up the balloon and release it. The air in the balloon propels the car. Students must also design the axles and wheels for the car so that it will roll and not just scoot across the floor.
How do you make a bottle racer faster?
If this happens, try wrapping masking tape around the bottle near the top and bottom, or putting a rubber band around the bottle near the top and bottom to improve traction. Pick up the bottle, wind the straw, and then release the straw while holding the bottle.
How does Newton's law apply to a balloon powered car?
Balloon cars rely on Newton's Third Law of Motion . As the air rushes backward out of the balloon it pushes the car forward in the opposite direction with an equal force.
How do you make a toy car move by itself?
Put a magnet at the bottom of the tabletop so that the pole of the magnet in the car and the pole in the magnet under the tabletop are opposite poles. If the magnetic poles are not opposite each other, the car will jump away from the magnet in a random direction.
How do you make a Rubber Band Racer car?
Take a rubber band and loop it through the lollipop stick near the front axle. Hook the other end of the rubber band around the skewer tip attached to the back axle. To wind up your car, carefully turn the large wheels of the car so that the rubber band winds around the back axle. Let go and watch your car spin off!
