What’s the best way to finish a bottle of wine in the fastest time possible?

At my college there is a challenge to finish a 750ml bottle of (cheap) white wine as quickly as possible. My current time is about 40 seconds; a time of below 25 seconds is considered very good. Is there a particular technique that I could use in order to get an exceptional time such as sub-20 seconds? (For example doing a tornado). I can practice with water if it’s a technique that requires practicing.
