Ok, lets try a combined approach. Beer in an upside down grapefruit skin with a cucumber floating in it, wrapped in aluminium foil on a bed a crushed egg shells, with a battery attached.
I don't have anything aluminium to give it a try though!
cucumber is a fruit. fruit acid rots aluminium and it wont do the ground any favours. If the fruit has absorbed aluminium never eat it because aluminium rots the brain.
