Abstract
In aspects of a multi-use recyclable drinking straw, the drinking straw has an elongated housing with a continuous sidewall that encloses a void space conducive for conducting a liquid, and the continuous sidewall is formed with recyclable material that is both rigid to sustain use as a beverage straw and collapsible for recycling. The drinking straw also has a contact area of the elongated housing that provides a temperature indication of the liquid, where the temperature indication serves as a hot beverage safety warning to a user of the drinking straw. The multi-use recyclable drinking straw can include a first configuration as a beverage straw with the continuous sidewall of the elongated housing having an oval cross section, and can include a second configuration as a beverage stir stick, where the elongated housing is collapsible such that the continuous sidewall has a flattened cross section conducive for stirring the liquid.
