I saw a video claiming that if you put a 5 gallon bucket about half full of water in your car and throw some dry ice in it then close the door (obviously nobody inside the car) then the carbon dioxide replaces all the oxygen in the car killing anything that needs oxygen like bugs, bacteria and in turn also killing the smells bacteria makes. Is this actually real or just social media engagement bait?
