Q&A for How to Make a Toy Car

Yes, using a fan you can make it move by hooking it up with a motor.

You can cut out foam or sponge circles or you could use bottle caps.

I suppose you could use strong, clear tape or something similar, but glue would probably be the most effective thing to use.

Of course. Let your creativity run wild with this project.

Yes. I recently tried this and found the car cannot carry more than 100 grams.

It depends on how tight the rubber band is. If it is loose, tighten it more, and your car will go faster.

Give it a motor, and make sure the car is aerodynamic enough to move quickly.

Just pull or push the car in whichever direction you want it to go.

Get more bottle caps and recycle the old ones.

No, it doesn't. However, I would recommend using thicker cardboard.

The wheels can be bottle caps or anything round that will roll. Then you can use a skinny wooden rod or another material for the axle. Poke the perfect sized holes in the round object, slide the axles in, glue them, and you have wheels and axles.

You can get them at any stationery store. However, it depends on the country you're living in.

Yes, you can. I've done this and it worked just as well.

They are wooden skewers. You could try to use other materials, like bent paperclips instead if you don't have access to skewers.

Of course! If you have the skills to improve upon it, go for it!

Yes, you just need something that is able to spin and make the car move. Bottle caps work better because they are thicker. If you do decide to use cardboard, use thick cardboard.

If you use things that were recycled, it won't cost anything. But if you buy the parts, like a motor, it will cost more.

The majority of the materials used are waste materials. If you use a straw, for example, you can cut off the bendy part your mouth has been on and use the rest for your car.

Of course you don't have to paint the wheels! Nor do you have to paint the car. You can paint the car to make it look more like a real car or make it look more personalised but it makes no difference if you don't paint the car.
