How to make "hot ice"
Ooo, I remember this from chem class, instant freeze a drink "party trick"
You put a carbonated drink, like beer or soda, into the freezer for about 3 hrs or so like the instructions in the details for this video say. It is a solution of a carbonated liquid with a lower freezing temperature so that it won't freeze even after being in the freezer for a while. However as soon as you take it out, it is unstable and if you knock the carbon out, it becomes a solution with a higher freezing temperature so it reacts to the cold it has been exposed to and freezes instantly. Right...? Something like that? Goodness chem was fun.
and this is just cool:
