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.
