Vlogmas 8 2023 - The invincible slugs part 2 (copper resistant slugs?)

I bought copper tape to repel slugs from my pot plants but slugs were still getting to them, so I put this strip of copper tape in front of a slug to see what happened. It seems that either the tape I bought isn't real copper, or the copper repelling slug idea is a myth. At least with the slugs around me. I did think of the possibility of there being a coating over the copper on the tape which is the main reason I decided to measure its resistance. It also discoloured under a drop of vinegar (you can see the results from the drops in the clip where I measure the resistance), so my calculated guess would be that this is indeed copper but the slugs just don't care. Maybe there will some use for the copper tape in a future electronics project but I'm not wasting any more on the slugs!
