To eat small items with rubber bands, you can use the rubber band to create a makeshift pair of chopsticks. Simply wrap one end of the rubber band around one finger and then loop the other end around your thumb, creating tension between your fingers. This will allow you to pick up small items like nuts, berries, or pieces of fruit. Alternatively, you can use the rubber band to create a small pouch by stretching it over the opening of a cup or container, allowing you to easily pick up and eat small items without them rolling away. **

Rubber tires have small hairs, also known as "vent spews" or "vent spits," as a result of the manufacturing process. These hairs are formed when the hot rubber is forced through small holes in the mold during the tire production process. They serve as a release agent to help the tire release from the mold more easily. While they may seem like a cosmetic flaw, these small hairs do not affect the performance or safety of the tire. **
