Science project car

For my current event science blog I will be explaining how I am going to build my car for the upcoming science project. Most of the car will be made out of cardboard and some other materials. The body of the car will be fully made of cardboard so it will travel at a faster rate since cardboard is lite. Im going to use a wooden round rod to stick between both sides of the cardboard for my wheels. Originally, I was thinking of making the wheels out of styrofoam but we are not allowed too since it is so bad for the planet. I choose to use wood instead and carve the wood by myself to make it round and then attach both sets of wheels on the rods. The rods will be in the front and back. All the wood will be made by myself, I have alot of experience with tools. When the car is finished I estimate it should be very lite weight and fast. The body and rods wont be too big since I need to fit the car on the ramp.
