Could you get a shock on your knuckle
PHILADELPHIA 1752 Benjerman Franklin tried to get an electric shock from friction in the sky on his knuckle from a key.To see if you can make enough to make a shock of static electricity on his knuckle .In his lab he used a generator to make static electricity on his knuckle he succeeded but wanted to make it bigger.Franklin took it outside.Franklin said "Wait until the next thunder storm and you'll see."He thought he could charge enough energy from lightning to get a spark on his knuckle like he did in his lab.If Franklin did this experiment in a thunder storm he would've not survived.Thankfully for him there was no lightning or rain to kill him.
