Distilled spirits like vodka and gin have a high alcohol content (typically 40%+ abv) and will not freeze in conventional freezers. Luckily conventional household freezers are plenty cold to freeze water. Submerging a full bottle of gin within a container of water and freezing we are able to selectively freeze the water creating a sheath of ice around our bottle!

So, you fill a balloon with water, and the tupperware with water, then put the baloon in the tupperware and froze it all
Them removed the balloon?
While your instructable is a fun idea, I found several problems when I tried to follow your steps.
First, my bottles would not stay centered inside the 2 liter mold, and would fall to one side. (I tried it with a variety of shapes of bottles, but no short squat ones like the one you show) Do you have a solution for this?
Second, my bottles would fall over as the ice melted. Even though they had flat bottoms, the ice wouldn't melt perfectly, and as the bottom melted it would cause the bottles to lean.
Any suggestions would be helpful.
If your bottles are more slender are having problems standing up try a 2-step freeze process. First pour water into mold only to cover the 'legs', freeze. Once frozen place bottle into mold, the previously frozen water will leave a flat surface for the bottle to rest on, add water to top and freeze again.
As for melting, my booze doesn't last long enough during a party to experience this problem. Best to have a few on hand if they're going to be out for a while and rotate.
Thanks for trying it! do you have any pictures?

Though not the same as a World Expro the Olympics will be pretty awesome too. Maybe I'll grab some merchandise, but everything I've seen so far looks tacky :(
