Find out why touching a doorknob can give you a surprise zap! Scuff John's foot on the carpet to build up static charge and see how electric charges jump to metal.
🎮 Try It
• Use the Leg slider or drag John's foot across the rug to pick up negative charges from the carpet.
• Watch how electric charges spread evenly throughout John's entire body as more charge enters.
• Use the Arm slider to move his finger toward the metal doorknob until a spark jumps across.
🎯 Your Mission
Build up only a tiny amount of charge and see how close John's finger must get to the doorknob before a spark triggers.
