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!

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.
ReplyDeleteThis is so cool! I've actually done this before on accident and know I know why it happened!
ReplyDeleteI never knew you could do that, Its never happened to me but now I know how to do it and enjoy a nice homemade slushy over break, thanks for the quick lesson!

I agree with Perley! I will definitely be partaking in home slushy making, thanks!
