How do you make a CO2 car?

How do you make a CO2 car?

  1. Step 1: Create Design. To create my design, I used CorelDraw x3.
  2. Step 2: Print Design and Cut. I then laser printed my design on the wood, I used a saw to cut it out.
  3. Step 3: Drill Holes.
  4. Step 4: Add Axels.
  5. Step 5: Use Washers.
  6. Step 6: Add Wheels.
  7. Step 7: Add CO2 Cartridge, and GO!
  8. Step 8: Ask Questions!

How can I make my CO2 car go faster?

Simply put, the less weight your dragster has, the faster it will go. This is the most important factor that will figure into your design. Keep it light! Thrust: The gas escaping from the CO2 cartridge in the car.

What is the best shape for a CO2 car?

Sphere – A very good aerodynamic shape because of it symmetrical shape. Which allows air to flow over it’s surface with very little disruption to the air stream. A combination of basic shapes will yield the best results. This equation has to do with how much weight is over the front and rear of the vehicle.

What are CO2 cars made of?

CO2 dragsters are made of lightweight material usually balsawood or basswood. They are propelled down a track by compressed carbon dioxide gas.

What happens when you puncture a c02 canister?

You will have to re-inflate your tyre with normal air, which includes larger molecule that leak out slower. If you don’t use all the CO2 gas in the cartridge, it will leak out over the next ~30 minutes approximately.

How do you reduce drag on a CO2 car?

Three Things You Can Do to Reduce Drag in CO2 Cars

  1. Golf Balling. Covering the surface of your car with small, semi-circular pits (“golf balling”) does two things.
  2. Get Low. The bottom of your car experiences just as much drag as the top, so make sure to keep things smooth and straight all the way around.
  3. Sleek Over Small.

What is the best length for a CO2 car?

You need to have at least 60 feet without any obstructions. Any shorter distance than this, and the cars will destroy themselves upon finishing a race. The optimum track length is 66 feet (20 Meters), which is in scale with real dragstrip lengths of a quarter mile.

Which Newton’s law makes a CO2 car work?

Sir Isaac Newton’s third law of motion states that for every action (or force) there is an equal reaction (or opposing force) in the opposite direction. CO2 cars are propelled by carbon dioxide rapidly escaping from the cartridge. The cartridge is positioned in the car so that the escaping gas moves rearward.

How much force does it take to puncture a CO2 cartridge?

CO2 liquefies at a pressure of 70 bar at 2500 C.

How do you make a CO2 car launcher?

CO2 car launchers can be purchased online or at a local hobby shop. However, the mechanics of a launcher are simple enough that almost anyone can one at home. Cut a plywood board that is one-quarter-inch thick so that it is six inches long by three inches wide.

How do I incorporate CO2 racers into my Maker curriculum?

In order to incorporate CO2 racers into your Maker curriculum, you need three things: cars & parts, the launcher & track space. I’ll tell you how I made mine after the jump. A CO2 car starts off as a “blank”. “Blanks” can be made out of any number of materials in any size the teacher deems necessary.

What are CO2 powered dragsters?

CO2 Powered Dragsters are little cars that students can design, build, test, modify and race and that “impersonate” the real life AA Fuellers in their speed, power and explosive fun! The cars travel down a 20 m track powered by 8 gram CO2 gas bulbs

How do you run a rocket car on hardwood?

Simply hit the hardwood strip in the center with a hammer and the pin will pierce the Co2 canister, releasing the gas and sending your rocket car on its way. Rocket cars need long, smooth flat tracks to run.
