Observing Corrosion Test Results

What happens here

After a period of time (implied to be several days, as results are shown), the presenter extracts the wires from each solution. He observes that the wire submerged in the 'Green Gobbler 20% Vinegar Weed Killer' has visible black discoloration and pitting, indicating significant corrosion. In contrast, the wire from the glyphosate solution shows no signs of corrosion; it remains shiny and clean. He wipes both wires with a paper towel to highlight the differences more clearly. This visually demonstrates the corrosive nature of the organic vinegar on metal components.

Goal: Determine the corrosive effects of organic and chemical weed killers on metal.
