Introduction

Story about the Greeks or other ancients and what they knew about triboelectricity?

From the wikipedia:

"The triboelectric effect (also known as 'triboelectric charging') is a type of contact electrification in which certain materials become electrically charged after they come into contact with another different material and are then separated (such as through rubbing). The polarity and strength of the charges produced differ according to the materials, surface roughness, temperature, strain, and other properties."

The first to organize a series was Volta in 1779. Modern lists give:

(Most positively charged) (Small negative charge) Acetate
Human skin Wood Rayon
Leather Lucite Synthetic rubber
Rabbit’s fur Amber Polyester
Glass Sealing wax Styrene (Styrofoam)
Quartz Acrylic Orlon
Mica Polystyrene Plastic wrap
Human hair Rubber balloon Polyurethane
Nylon Resins Polyethylene(like Scotch tape
Wool Hard rubber Polypropylene
Lead Nickel Vinyl (PVC)
Cat\'s fur Copper Silicon
Silk Sulfur Teflon
Aluminum Brass Silicone
Paper (Small positive charge), Silver Rubber
Cotton (No charge) Gold Ebonite
Steel (No charge), Platinum (Most negatively charged )

Luigi Galvani

In 1783, according to popular version of the story, Galvani dissected a frog at a table where he had been conducting experiments with static electricity, Galvani's assistant touched an exposed sciatic nerve of the frog with a metal scalpel, which had picked up a charge. At that moment, they saw sparks and the dead frog's leg kick as if in life. The observation made Galvani the first investigator to appreciate the relationship between electricity and animation — or life
