In some biological experiments where it is necessary to kill a mouse, sometimes this is done by asphyxiation using carbon dioxide gas. That is always struck me as being immensely cruel. The mouse must be an agony from breathing in that atmosphere.

That, and you can actually tell you’re suffocating. Since your body can’t detect lack of oxygen, only presence of CO2, most any other gas would be a painless drift to sleep.

Yeah. I once read That an inspection team tired of suffocation well looking at one of the fuel tanks for the space shuttle. They were inside the tank, which had been purged with nitrogen. They were unaware that the tank was devoid of oxygen, And so they conducted the inspection for a short while, and then fell unconscious and suffocated.

I've done inspections and repairs inside fuel tanks that had a nitrogen generating system; We wear a gas detector that constantly monitors stuff like 02 levels, vapor concentrations, ionizing radiation etc. We dont even enter before taking a reading. If 02 gets below 18.5% or above 22% it will start flashing and sounding a (quite loud) alarm. This is worn in addition to all kinds of rules about tank entry: Gotta have a spotter make contact with you every 5 min, gotta have forced air ventilation or SCBA, gotta notify security of the entry operation so they can direct the rescue personnel if something goes wrong, etc.
It's fun work, imo. But yeah, it is actually quite dangerous.

Ah yes confined space entry procedure, really don't miss it lol. The best part was when my boss looked me in the eye before my first time as the entrant and told me "we don't rescue, we recover."

I’ve always found pinching my nose while burping helps prevent the spicy soda nose burn. The science makes sense

Carbonic acid is produced when the CO 2 is forced into water, making soda water.

Finally an answer to a question about which I genuinely never knew I wondered. Big belches always burned my nose and I never thought twice about it. This one might go down as an actual fun fact.

Carbonic acid was the acid responsible for acid rain.

Acid rain is caused by sulfur dioxide and nitrogen oxides, not carbon dioxide. However, carbon dioxide is responsible for ocean acidification.

A common mistake for new homebrewers is to take the trap out of the fermenter to "get a good whiff" of their beer. Pure CO2.
