How do you get your co2 license?

Question

and whats the requirements?

Answer 1

License?

For CO2?

You don't need a license to buy CO2!

They sell CO2 cylinders anywhere they sell bb guns.

Like Walmart!

If it's bulk CO2 you are looking for,

Try your local soft drink fountain supplier or bottling company, or look in the phone book under welding gasses. Failing that, try the local ice plant.

CO2 isn't regulated,

you EXHALE CO2...

you're thinking of Nitrous Oxide or Freon!
