I put this Corona in the freezer for about three hours, took it out, and then tapped it on the counter top. It's probably the coolest at home experiment to show off at party. Everyone that sees this thinks there's some sort of gel inside, but there isn't, just the process of "super cooling". Leaving the bottled beverage in an environment that is as cold or colder than zero degrees centigrade causes the liquid molecules to achieve a state of temperature less than zero degrees centigrade. When the bottle is tapped against the counter top it disturbs the molecules and causes an ice crystal to form. This causes a chain reaction to occur hence the freezing of the whole beer.

Try It Yourself:
1. Get a bottled beverage, glass or plastic, preferably glass. (non-diet/diet soda, Martinelli's, Beer, etc.)
2. Put it vertical standing inside a freezer for three hours. (Making sure that the freezer does not shake because this could disturb the process!)
3. Take the beverage out and tap it against a hard surface.
4. Watch the magic happen before your eyes and don't worry about wasting your precious liquid, it's still good to drink, frozen or not.


always read the label
