You can build your own racer cars at home using a wide variety of materials. If you have a family member at home with you, you can build different types of cars and race them! Below you will find examples of how to build cars powered by the tension energy stored rubber bands, chemical energy stored in batteries, and even air powered cars (using Newton's 3rd law of motion)!
Keep in mind that you have the freedom to mix-and-match designs and materials! For example, if you don't have a hot glue gun, is there another material you can use, like tape or super glue? Don't feel like you have to follow the procedure or video exactly. Use this as an opportunity to not only problem solve, but to add your own creative elements to whatever you build!
Note: For some of these designs, you will need parent/guardian supervision!
Rubber Band Racers
See how you can make a race car powered by rubber bands below. Remember, you can mix-and-match designs, or come up with your own! These are just ideas to get you started.
Battery-Powered Cars
If you have access to (or can buy) batteries, a battery holder, and a small motor, these cars are a great option. If you have a small battery-powered fan you don't use, you can repurpose the motor and propeller for your car. Or, if you are interested in this project, and your family is able to buy materials, you can easily purchase them online. Remember, you can mix-and-match designs, or come up with your own! These are just ideas to get you started.
Balloon-Powered Cars
Rather than using stored energy to power a car (like the previous examples), you can use Newton's 3rd law of motion, which states that for every action there is an equal and opposite reaction. Basically, what this means is that as the air escapes the balloon it pushes "backwards," causing your car to propel forward!
