A method of making a pressurized packaged liquid beverage including filling a container including a one-way valve with a liquid mixture including a base liquid and a gum; sealing the container; introducing a volume of gas through the one-way valve after sealing the container; and agitating the container. When the container is opened, the liquid mixture increases in volume and separates into a liquid phase and a drinkable foam phase, which may persist for an extended period of time. The base liquid includes milk, coffee, fruit juice, or mixtures thereof.

In an example implementation, a substance detection device includes a chamber with chamber walls, a chamber top, and a chamber bottom. A substrate comprises imprinted nanostructures positioned within the chamber, and the substrate is coupled to the chamber walls to form the chamber bottom. An inert gas is sealed within the chamber.
