Abstract: Disclosed are various embodiments of cups and straws for infusing a substance into a liquid during consumption. In one embodiment, the cup includes an elevated platform that comprises a perforated surface and a cavity for a straw. The elevated platform may be positioned in the cup to retain a collection of the substance. When the cup is filled with the liquid, the platform is configured to facilitate the substance dissolving consistently throughout the liquid. In another embodiment, the straw includes a main channel for liquid to flow and a reservoir retaining the substance.
