"I have always heard the term dry ice, but quite frankly have no clue what it is made of, where it comes from, or even what its main purposes are. Nor have I ever seen any dry ice.Sigh...."You may know all these things and think I am a very uninformed and unintelligent human, but I don’t care."
“Are you vaping, man?”
“No, it’s the ‘smoke’ from the dry ice.”
The same effect could be had with most decent higher caliber rifles.
But having shot a few 50BMG rifles it is a lot of fun.
Another apparent failure of our education system. It's frozen carbon dioxide, as my grade school children already know.
You should care. It's never too late to learn.
Dry ice, sometimes referred to as "cardice" (chiefly by British chemists), is the solid form of carbon dioxide. It is used primarily as a cooling agent. Its advantages include lower temperature than that of water ice and not leaving any residue (other than incidental frost from moisture in the atmosphere). It is useful for preserving frozen foods where mechanical cooling is unavailable.
Dry ice sublimates at 194.95 Kelvin (−78.5 °Celsius, −109.3 °Fahrenheit, and 350.91 °Rankine) at Earth atmospheric pressures. This extreme cold makes the solid dangerous to handle without protection due to burns caused by freezing (frostbite). While generally not very toxic, the outgassing from it can cause hypercapnia (abnormally elevated carbon dioxide levels in the blood) due to buildup in confined locations.
Dry icce is the biggest threat to humanity there is! Run away!
Dry ice.
It’s what I buy then crush and refill my SodaStream cylinders with.
You can buy it at one of the local groceries here, buddy. And he likely can near where he lives. I helped a friend who was going to be traveling for a couple days get some a couple months ago. She knew about dry ice, but didn’t know where to get it (at Publix, here). Keeping her duck fat fresh was important! She had about 2 quarts. A serious foodie.
If I melt dry ice can I go swimming without getting wet? - Steven Wright
ok, google the stuff people. sheesh. No excuse in not knowing sht these days
This is quite interesting. Maybe this could be a firefighting idea in the making, using small airbag explosive charge to spread a cloud of CO2 in case of fire or lob dry ice from fire trucks.

All those CO2 ice fragments exploding into the ambient air while “melting” looks like a white phosphorous grenade exploding.
