How to Make a Tiny Race Car for School
This DIY Rubber Band Racer is one of our favorite kid-friendly activities to do as a family. Our kids really like to make DIY toys and the best part…you can make it with items found around the home. There's nothing like seeing the smiles on your kid's faces as they make homemade toys.
We actually started a recycling program in our home to see what raw materials we could use to upcycle and make something new! The kids just love to see what they find around the house to put into our "kid activities" bin. Plus, it's an extra bonus to our natural resources, it limits the amount of waste and reduces the landfill space (helping to reduce solid waste & teaching the kids about waste management is a win-win. Good for us, good for the planet.)
This is probably one of our favorite rubber band toys we have made. It might be our favorite DIY kid's toy we have made (we've made plenty of DIY wooden cars, too).
Here are the items needed for your DIY race car and the step-by-step directions for making a DIY Rubber Band Racer.
I'll include affiliate links to find what you need on Amazon, as well.
- 2 straws (this will be the frame of the car). These are recycled paper staws.
- 4 toothpicks (or wooden skewers). I have also used a paper clip.
- 4 container lids (from a milk container or prescription caps)
- Rubberband (or Rainbow Loom Bands-great way to use the millions that are just lying around)
- Hot glue gun (I used a low temp since our 6-year-old was helping)
- Drill (with small drill bits)
First, I used a ruler to figure out where I wanted the placement of the holes on my straws because this is where the toothpicks are going to go (see picture below).
Note: Each straw will have four holes. Two holes are drilled at each end of the straw.
On each end of the straw, I drilled the first hole 1/2 inch in from the end and the second hole is drilled one inch from the end. I repeated the process on the opposite side of the straw. You will repeat this process for the second straw. Both straws should look the same when you are done.
What are the holes for?
The first hole (the one closest to the end, 1/2 inch back) will be used for your wheel axels. These holes should be made a little larger and will allow your wheels to move freely.
The second set of holes (the ones that are 1 inch back) will be used for the structural supports. These holes should be a bit smaller and the toothpick should fit snug into each straw.
- Once you have all the holes made in your straws you can move to the assembly of your car frame.
- You will place a toothpick through each structure hole (the hole that you marked at 1 inch or the 2nd hole from the end). I recommend pushing the toothpicks all the way through so the pointed tips are sticking out on both sides.
- Next, use your hot glue gun and glue the toothpicks to the straws. I would just glue the inside portion first and let it dry.
- Once dry, cut the pointed ends off your toothpicks and place a little glue on the outside section of the straw.
Now that you have the structure built, you work on and add the wheels. this is where the lids or caps come in. Most of the caps that you will find have a mark in the center. This is a great and perfect place to drill the hole to make the axels for your cars.
You will want to drill the hole in the center of each lid. This will be the same process as the holes you drilled in the straws. The holes in the wheels will be drilled just large enough for the toothpick to fit snug.
On one of the toothpicks, drill a very small hole in the center. Once the hole is drilled, you will place the toothpick ends (the point) that you cut off to make a peg (see picture below).
The peg will help when winding up the rubber band car to make it go. This toothpick will be your rear axle. Make sure to attach the larger caps to this one if using different sizes for the wheels.
- Now you are ready to assemble.
- You can start with the rear axle.
- Place the toothpick in each hole, and attach each wheel.
- Note: At this point, you will want your peg to be in right in the center.
- Once the toothpick is in place you can attach each wheel and glue them into place.
- Repeat this step for the front axle.
- Note: you may want to add some more glue to the caps on the rear axel to give it some added weight. This will keep the car tires from just spinning when the car is ready. Another tip would be to use a little Playdough to pack in the caps.
Now that your car is built… Attach the rubber band to the front structure support. I personally did not have any rubber bands, so my son made me a quick one out of his Rainbow Loom bands.
Once attached, place the opposite side on the rear axel peg and slowly wind up the tires to test it out.
Now it is time to let your kids have some fun & learn about force, motion, kinetic energy, recycling and more!
They will love playing with their new car! You can decorate it (our kids made the 'wheels' into United States flags one time, and other times they've just done a little babble dabble with paint to create new designs).
Hint: Be careful if you make it while their friends are around… they will start placing orders! check out our video & watch it go!!
