Abstract: An expansion chamber includes a chamber body having a top portion above a bottom portion cooperatively forming a hollow chamber volume configured to temporarily contain an expansion of bubbles during an aeration process for aerating a liquid, including wine and other alcoholic beverages. The bottom portion has a bottom opening configured to engage an opening of an uncorked and/or opened wine bottle. The top portion has a top opening. The hollow chamber volume is configured to be in fluid communication with an inside of the uncorked and/or opened bottle when the bottom opening is engaged with the opening of the uncorked and/or opened bottle. A maximum inside diameter of the hollow chamber volume in a horizontal plane with respect to the uncorked and/or opened wine bottle set upon a horizontal surface is cooperatively formed between the top and bottom portions, wherein the maximum inside diameter is at least 2.50 inches.

Abstract: A rigid frame is sealed in a waterproof manner to a pair of pants and/or waders, where the frame forms a frame aperture separating an outside from an inside of the pair of pants and/or waders. A rigid lid is pivotably connected to the frame and configured to engage the frame aperture. The rigid lid in an open position allows access through the frame aperture and the rigid lid in a closed position does not allow access through the frame aperture. A seal is disposed between the frame and the lid forming a waterproof closure of the frame aperture when the lid is in the closed position. A latch is pivotably connected to the frame and configured to retain the lid in the closed position. A spring is disposed between the latch and the frame, the spring biasing the latch to retain the lid in the closed position.

Abstract: A rainproof pair of pants or a waterproof pair of waders includes a rigid frame sealed in a waterproof. The frame forms a frame aperture and a rigid lid is pivotably connected to the frame. A seal is disposed between the frame and the lid forming a waterproof closure of the frame aperture. When the density of the frame is first set to be 0.04 pounds per cubic inch and when the frame and lid are scaled so an area of the frame aperture is first set to be 7.205 inches squared, then the following is true: a mass moment of inertia taken at the frame center of mass about the frame x-axis is equal to or greater than 0.19 pound square feet; and a mass moment of inertia taken at the frame center of mass about the y-axis is equal to or greater than 0.27 pound square feet.
