J-Stace The Science Ace Makes Super Cool Soda

Join Jonathan every day at 9:20am on QC Morning for a new science lesson!

Hey parents! Looking for a substitute for your “science class”?
We recommend J-Stace the Science Ace.
Make the perfect slushy or milkshake with drinks in your refrigerator!
  • 1 (or 2) bottles of water, soda, or juice
  • Ice cubes
  • Glass
  1. Put the bottle into the freezer for 45 minutes.
  2. Wait 45 minutes.
  3. Test to see if it is supercooled: put an ice cube in a glass and pour a little liquid out of the bottle. If it is supercooled, it will turn the consistency of a milkshake.
  4. If it is still completely liquid, put the bottle back into the freezer with the lid screwed on for 15 minutes.
  5. Repeat steps 3 and 4 until you have a supercool treat. If your bottle freezes solid in the freezer, you can try the backup bottle (if you used two bottles) or run the frozen bottle under warm water until it thaws.
The Science Behind the Experiment
Water freezes at 32 degrees Fahrenheit, 0 degrees Celsius. It is possible to bring it below 32 degrees F, but usually only for a little while, and only if there are no ice crystals formed in the water yet. Once the supercool water forms a crystal or touches another piece of ice, it freezes in a hurry!
Science Word of the DaySupercooling is the process of chilling a liquid below its freezing point, without it becoming solid. A liquid below its freezing point will crystallize in the presence of a seed crystal or nucleus around which a crystal structure can form.
