Homemade Slushies

Slushies are one of my favorite kinds of beverages, just because it is so funky and cool. I've always thought making slushies was complicated, until I found this gem of a video. 
So basically, to turn any types of soda into slushies, shake the soda violently and then proceed to place 4 16.9-oz bottles in a freezer set at -11ºF. What the shake does is to build up pressure in the bottle, and as you may recall, at higher pressure, substance freezes at a lower temperature. Therefore, after 3-4 hours when you take the bottles out, the soda will be colder than freezing temperature, yet still in it's in liquid form. What the accumulated pressure does is delaying the freezing process.Then, when you take the soda bottles out of the freezer and quickly remove the cap to release the built-up pressure, the soda will freeze rapidly at the sudden change to give you slushies. Pretty easy, huh?However, depending on the freezer you have, time and temperature may vary, so keep experimenting!

  1. I know what my next DIY project is going to be! On a more serious note, I love seeing the science behind things that we encounter (and love) on a daily basis. Too often science can feel removed from our daily lives with the long names of chemicals in strings of letters and numbers. Things like this allow us to reconnect the two.

  2. This is so cool! I've actually done this before on accident and know I know why it happened!
