About: Lightning Rod and House Electrostatic Apparatus
Made by Griffin and Tatlock Limited, this 1850s model demonstrates the importance of the lightning rod, which protects buildings by siphoning off the buildup of static charge from a storm cloud and directing the charge into the ground. The lightning would be generated by the adjacent Leyden Jar, a type of capacitator used to store electrostatic energy, and it would occur as electrons travelled between the two metal balls.
