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.
