What happens when you pump 20,000 volts into a watermelon? Two words. Pink Mist

The Backyard Scientist wanted to find out what would happen when 20,000 volts of electricity are pumped into a watermelon. What he and his friends got was a big explosion with a fine, pink mist captured in slow motion. They also pumped 20,000 volts into a raw steak and a potato.
