Steps:
- prepare fruit for experiment by squeezing it on all sides
- not hard enough to break skin
- do this to soften fruit
- not hard enough to break skin
- insert nails into fruit, approximately 2 inches apart from each other
- sharp end of nails should be in the center of the fruit but not touching each other
- do not pierce nails through other side of fruit
- sharp end of nails should be in the center of the fruit but not touching each other
- remove insulation around the bulb wires (the lead) so you can expose enough wire to wrap around the nails
- take one end of the exposed wire and wrap it around the zinc (galvanized) nail
- if wire slips off, use electrical tape to hold together
- if wire slips off, use electrical tape to hold together
- wrap other end of exposed wire around the copper nail
- take second wire, wrap one exposed end around the copper nail
- take other end of second wire and attach to the light bulb
