Electric chair
Electrocution was adopted as a quicker and supposedly less painful method of execution than hanging in the 1880s. The victim has their head and one calf shaved to reduce resistance to electricity before being strapped in across their waist, arms and legs. A moistened sponge is placed on their head and an electrode in the shape of a metal skullcap is secured on top. Another electrode is attached to their shaved leg before the power is switched on. 2,000 volts pass through their body, paralysing the respiratory system and causing cardiac arrest.
