Placed a bottle of grape flavored Propel outside on my porch overnight. Temperature on the morning of February 22, 2013 dropped to -6C. The liquid did not freeze and it had very little solute in it so the lack of freezing could not be attributed to the colligative property of freezing point depression, instead the liquid was supercooled. I brought the bottle in the house and stuck it in my freezer for 3 hours to make it cool to -10C and poured the liquid over an icecube and a rope like stream of slushy ice appeared. Eventually the liquid was allowed to freeze the liquid in the bottle. The temperature of the liquid rose from -10C to zero Cesius as it froze because the newly created hydrogen bonds give off heat.
