yea theres gunan be water, my feiend says that to stay under there you have to tilt ur head just a litle, like 30 degrees. i can picture me slipping and going under. ill be high, with very little oxygen becuase weve been beathing in the same 3 cubic feet of air for 10 min, and slipping around under the water becuase hottubs have lots of seats and bumps ect. i think weel just smoke in the hottub and run around in the snow
