Vilcus dactyloadapter was developed specially for people who enjoy closing electrical circuits with their own fingers.
Many people get a kick out of direct contact with AC power supply. To that end, people normally use U-shaped fragments of bare wire, paper clips or even usual metal forks. All these gimmicks are unreliable, short-lived and, most importantly, tend to cause short-circuit failure or even inflammation. You can even share the excitment with yr friends with a multi user adaptor.
