speed bottling 

A game in which between 4 and 10 people get hammered and sit in a spa or pool, or any large enough body of water with an empty plastic bottle. The plastic bottle is rapidly pulled under the water in the center of the spa, then released, launching it into the air. The aim of the sport is to get the greatest number of catches in 60 seconds. The current world record is 51 catches.

You may not catch the bottle if it was you who released it, nor if it is partly in the water.

This is an example of speed bottling, before the bottle is realesed
