Directions

Start by cutting a rectangle out of cardboard. This is where your amazon box stash will come into play. This piece is going to be the base of the car. We did ours about 1 ½ size of a deck of cards.

On one end of the body of the car you are going to cut two slits, about ½ an inch apart. This will be in the middle of one end.

On the opposite side, you are going to cut a small rectangle out of the edge. See picture.

Now it’s time to make the axis of the car. We used a dowel cut into two. Scissors wouldn’t cut this, but wire cutters did. You can also use toothpicks if you don’t have dowles on hand.

When this was done, we made the Axle Carriers. This is where the straws come into play. Cut them to fit the spaces as shown in the picture. I honestly cut what I thought would fit, used hot glue to attach and then cut down to size.

When these are attached, start on the side with the notch cut out. Slide the dowel in one side of the straw, and then through the other side. Tie the rubber band onto the middle of the dowel on the notch.

Slide the dowel onto the other side also.

Next, cut out 4 circles from cardboard to be wheels.

Glue these onto the ends of each of the dowels.

How to make a rubber band powered car

When the car is complete, take the rubber band end that isn’t attached and connect it to the two slits on the other end of the car. When you are ready to play with the car, you will pull the car back and the rubber band will wrap around the front axle. When it is wrapped a few times, let go of the car and the wheels will spin, pulling your car in the direction it is pointed.

You made a car move all on it’s own. How cool is that?

Engage kids in a fun and educational STEM activity designing their a rubber band car to learn about simple machines & problem solving.

Not only is this a fantastic STEM activity, it is also a confidence booster for kids. If you teach them that when they put their mind to it and work towards something, following the directions, they can create all on their own!
