You can cut a straw into smaller pieces and use them to hold lotion, melting the ends shut. This is especially useful when you need to travel light (such as camping) and allows you to make single-application packages of antibiotics and other lotions. See the full tutorial: DIY - Single Use Antibiotic Packs. Found via Trash Backwards on Pinterest.
This applies to Plastic straws.
