Whenever I get dry ice from a delivery package, I like to have fun with it with the kids, mixing the dry ice with water, to create a mysterious witch-cauldron smoke.
So I wonder why this happens? I guess this is where my science degree could have come in handy, had I remembered most of the stuff I learned in college (sigh).
After reading up on the internet, I will spare you guys the trouble of looking for that information. One major warning about dry ice though is that dry ice is ridiculously cold (double the cold of regular ice). It is so cold that it will "burn" off your skin, so watch out and be careful with it!
The reason why dry ice creates this smoke and fog is precisely because of this coldness. Because the dry ice is so cold, adding water, which is so much warmer, instantly converts the ice into carbon dioxide and water vapor. I'm sure many of you will see this once October rolls around and Halloween festivities are underway!
Have a good one!
