Whenever you are in a hot tub
Sam and Katie's Picturesque Palace
With nothing better to do with the empties as we were sitting in the hot tub, we decided to float 'em. This turned into a good old fashioned game of sinkers and floaters, which I would reccomend to anyone. Make sure you really crank up the jets otherwise you might be in for a long game and if it lasts too long your just going to have a hot tub full of empties and that's no fun now is it?
