Place a magnet at the bottom of the tabletop such that the poles of the car’s magnet and the pole of the tabletop’s magnet are opposite poles. The car will jump away from the magnet in a random direction if the magnetic poles are not opposite each other.
How can you get a cardboard car to move on its own?
To make your cardboard car move, follow these steps: Simply tilt your Coke can in one way over and over to allow the rubber bands to store some potential energy. After that, park your automobile on the ground and release the can. The Coke can should spin, releasing all of the energy trapped inside and propelling your cardboard car forward!

What can you use to accelerate a toy car?
Rub the axles and their connections to the automobile and wheels with a little amount of silicone lubricant on the end of a cotton swab. During the application, spin the wheels to coat the axle on all sides.
To check if the toy car is rolling straight, move it forward on a flat surface. To adjust the track, bend the wheels or axles slightly until the toy car is driving in a straight line.
To improve traction, scuff the tread portion of the wheels with a small piece of fine sandpaper. To scuff the wheels uniformly, spin them while sanding.
What is the best way to power a rubber band toy car?
You’ve undoubtedly launched a rubber band at least once by pulling one end back and releasing it into the air. Have you ever considered rubber bands as a fun method to learn about physics and engineering? In this project, you’ll build a rubber band-powered car to find out.
A rubber band stores potential energy when stretched. It holds elastic potential energy, which is the type of energy that is stored when a material is deformed (as opposed to gravitational potential energy, the type you get when you raise an object off the ground). That stored energy has to go somewhere when you release it all. Potential energy is converted to kinetic energy, which is the energy of motion, when you launch a rubber band across the room.
But what if you could put all that saved energy to good use? To make a simple rubber band-powered automobile, attach your rubber band to a simple machine with a wheel and axle. Chemical energy from fuel or electrical energy from a battery is transformed to kinetic energy of a moving car in real cars. The energy source for your model automobile will be a rubber band. To get your vehicle working, you’ll need to do some engineering. Challenge yourself to see how far your automobile can drive!
(Please keep in mind that this is an engineering design project.) The materials listed below are suggestions; however, you can use alternative ones.)
- Cardboard that has been corrugated
- two straws for drinking
- a pair of wooden skewers
- There are four CDs total (that are okay to get scratched)
- Rubber bands in various colors
- For testing your car, you’ll need a flat, hard surface.
- Glue gun with hot glue (optional)
- Cut a piece of corrugated cardboard slightly longer and wider than the length of one straw with care.
- Tape the two straws to the cardboard, one at each end, parallel to each other.
- On one end of the cardboard, cut a one-inch-by-one-inch rectangular notch. This will also take a section off of one of the straws in the middle.
- Each straw should be pierced with a wooden skewer. These will be the axles of your car.
- Cut four little squares from the sponge and place them on the skewers’ ends with care.
- To make wheels, attach CDs to the axles. Fill the hole in the middle of the CD with a piece of sponge, then use tape to attach the CD and keep it from swaying.
- Check to see if your vehicle can roll smoothly. Place it on a level surface and give it a gentle push. Adjust the wheels as needed to ensure that they are all parallel and do not wobble. How far do you think your automobile will drive if you use elastic rubber band energy to power it?
- Loop a rubber band around the exposed part of the wooden skewer in the middle (where you cut out a notch in the cardboard and straw).
- To keep the rubber band from slipping, tape it to the skewer. When the skewer spins, the rubber band should rotate as well.
- In the centre of the piece of cardboard, cut a small slot.
- Insert a paper clip into the slot.
- Hook the rubber band’s free end onto the paper clip.
- The axle that is attached to the rubber band should be wound up. Start by pinching the rubber band on the axle if necessary to keep it from slipping.
- Place your car on the ground and let go of the axle. So, what happens next? Is your vehicle moving forward? How far will it take you?
- It’s time to do some troubleshooting if your car won’t move.
- If the rubber band doesn’t seem to be unwinding, tighten it up and try again. To modify the rubber band’s tightness, consider moving the paper clip hole to a different spot.
- If the rubber band unraveled but the axle did not rotate, it is possible that the rubber band was not tightly fastened to the skewer. Try creating a tight knot or using hot glue to secure it to the skewer.
- It’s possible that there wasn’t enough friction between the CDs and the ground if the wheels spun but the car didn’t move forward at all. Attempt to use the vehicle on a different surface. If that doesn’t work, try stretching rubber bands around your CDs or dabbing a bead of hot glue around the borders to give them additional hold. (Before testing your car again, let the glue dry completely.)
- Continue to play around with your vehicle. Make minor adjustments and retest it. How far can you drive the car?
- Extra: Consider your rubber band-powered car’s “fuel economy.” Cars that run on gasoline calculate their fuel economy in miles per gallon, or how far they can drive on a single gallon of gas. Instead of gasoline, your car gets its energy from a stretched rubber band. How would you calculate the “fuel economy” of various designs? For example, how far can your car go per initial axle windup rotation? How does this vary as the rubber bands or paper clips are moved around? What makes the most sense in terms of fuel economy?
- Extra: Experiment with several types of rubber bands to see which ones will best power your automobile. Is it better to use long or short ones? Do you like thick or thin ones?
- Extra: Experiment with different materials when building your car. What happens if you use bottle caps for wheels instead of CDs, and pencils for axles instead of skewers?
- Extra credit: Work on this project with a group of friends or relatives. Everyone can construct their own vehicle and then compete to see who can travel the farthest distance.
- Extra: Instead of using a rubber band, you may use a balloon to power your automobile. Instructions can be found in the “More to Explore” section below.
When you wind up the car’s axle, the rubber band is stretched and potential energy is stored. When you let go, the rubber band begins to unwind, converting the potential energy into kinetic energy as the car moves forward. The more the rubber band is stretched, the more potential energy is stored, and the car should travel further and quicker.
All of this sounds fantastic in principle, but you may have found it challenging in practice. Several factors can cause your car to malfunction. The wheels can wobble or jam if they are not properly aligned, preventing the car from rolling smoothly. The rubber band can snag on the wooden axle, preventing the wheels from turning. Even if the wheels do spin, there may not be enough friction with the ground to keep them spinning in place, causing the automobile to remain stationary. All of these obstacles can be addressed with a little engineering work!
