Slug experiment with copper tape.

Today my friend and I set up an experiment to see if slugs would cross copper tape that is sold as a slug deterrent. Slugs were placed into the square in the middle of the tinfoil dish or in the tub.
Outcome- some slugs did resist going over the tape but on the whole as can be seen by the pictures the tape didn't work. The larger slugs seemed to ignore the tape completely.
