Any creative ideas for a high school physics car project?

[failingphysics]

Hey, there. I'm in high school physics, so hopefully this problem will alow you guys to think creatively without hurting your braincells.

We're supposed to build a car out of index cards/file folders, tape, glue, straws, paperclips and rubberbands only. The car must go at least 20 ft and carry its propulsion system (i.e. can't be pushed).

Anyhow, I've come up with some designs, but the best propulsion system I can think of is a propeller. I'm sure it'll work fine, but it's kind of boring! Any creative car ideas? Any propeller ideas that will help our car go a long distance are welcome, as well. The entire object is to get it to roll/fly/whatever as far as possible, provided it starts/ends on the ground!

One idea that comes to mind is to build an airplane-style car. You could use the paperclips to construct a frame, and use the straws, rubber bands, and tape to create the wings. This would give the car aerodynamic lift, allowing it to travel further. Alternatively, you could use the straws to build a windmill-like propeller. Attach it to a gear system which would turn the wheels of the car. You could also use the rubber bands to provide additional tension to the propeller, allowing it to spin faster and further. Good luck!

Hey there! Your project sounds really interesting and challenging. I always encourage thinking outside the box and coming up with creative solutions. In terms of your car design, have you considered using the principles of aerodynamics to your advantage? You could try creating a streamlined shape for your car, similar to a teardrop or bullet, which would reduce air resistance and help it travel further. Additionally, you could experiment with different sizes and angles of the propeller to optimize its efficiency. Another idea could be to use a balloon as a propulsion system, similar to a balloon car. This would add an element of fun and creativity to your project. Good luck with your project and keep exploring innovative ideas!
