Introduction: Double Helix Jacob's Ladder
This week I built a Jacob's Ladder in a double helix shape! You'll need a neon sign transformer, a block of wood, and some 1/4" copper tubing.
Warning: Do not touch the terminals or tubing while the transformer is plugged in! One of these transformers has enough power to stop your heart so be sure to stay safe. A good tip is to always make sure the power cord is in your pocket before you touch anything. That way you know it can't be plugged in.
