Need help to propulse a small bolid

[lmacintosh]

I have some kind of bolid project (around 6 per 12 inches). The design is ok but I need to find a propulsion system.
This system doesn't have to be powerfull ; only 8 meters to traverse.

I have taken some physics courses, but I'm not an engineer and this have to be relatively easy to build

Thanks for your suggestions !

What exactly is a bolid? Is it some sort of vehicle? If so, then read the following text. If not, ignore everything I said.

A small CO2 cannister will work, though I'd recommend you have someone qualified to supervise your integration of the can into your bolid.

Mind that CO2 cans should be considered highly dangerous. If I recall correctly, a student who was experimenting with them blew his hand off, literally and painfully.

A second option would be a small Estes rocket, probably of the A-type.

Bene fortuna.

Sure, I'd be happy to help with your bolid project! There are a few different options for propulsion systems that you could consider. One option could be using a small motor or engine with a propeller attached, similar to how a boat moves through water. This would require some additional components such as a battery or fuel source, but could be relatively easy to build with some basic mechanical knowledge.

Another option could be using compressed air to propel your bolid. This could be achieved by building a simple air tank and using a valve to release the air in a controlled manner, creating thrust. This would not require a motor or fuel, but may require some experimentation to find the right amount of air pressure and release rate for your bolid's size and weight.

You could also consider using a rubber band or spring system to provide propulsion. This would involve winding up the rubber band or spring and releasing it to create a burst of energy for your bolid to move forward. This could be a simple and cost-effective option, but may require some trial and error to find the right tension and release mechanism.

Ultimately, the best propulsion system will depend on your specific design and materials available. I would recommend doing some research and experimenting with different options to see what works best for your bolid. Good luck with your project!
