For the noble and brave

This method works for spiders of all sizes

1. Get a glass cup (spiders cannot crawl on glass surfaces)
2. Trap the spider underneath
3. Slide a piece of paper (construction paper is recommended) underneath the inverted cup, being careful not to lift the cup and let the spider out
4. Slide your hand under the paper and cup, holding the paper firmly against the glass
5. Bring the contraption outside and remove the glass
6. Run away and wait until the spider leaves so you can retrieve your paper (do not litter!)
7. Do not forget to wash your cup!
