When you think about dry ice you may not think about the process of how a dry ice maker works, or the many other things that it can be used for. Personally my experience with dry ice has been to keep things cold and to use it to make fog.
Yes, fog. Dry ice with a little bit of water makes an awesome fog that we've used for my children's stage productions, and on Halloween for a scarier walk to our door for trick or treaters. Haunting music and a fan to help disperse the fog adds to the experience and it's something that's become expected in our neighborhood.
I didn't realize until I decided to do a bit of research that dry ice blasting is system that uses dry ice to remove things like varnish or adhesives. It does it in a way that is much more environmentally sound, since it doesn't use harsh chemicals or leave a residue. While this type of a machine wouldn't be something the average person may want to own, it is interesting to think about how something we assume is only for a limited use, has many other uses.
Dry ice was actually created in 1835, by a French chemist named Thilorier, it stayed in the world of science for about sixty years before it was noticed as a possible product for real life uses, like in railroad cars to help keep food from spoiling as it went from one destination to another It extended how far food could travel and helped reduce spoilage if there was a delay in the delivery schedule.
Learn more about the use of this frosty product and I hope it is as entertaining for you as it has been for me.
