High Voltage Does not necessarily have any straight definition.  High Voltage could be anywhere from 50 volts all the way up to a million volts   Here at ForceLabs high voltage is anything that can potentially maim or hurt me which I think is always a good rule to live by.  High Voltages have many uses such as providing power to your home, X-rays, lasers and the like but in our case its for experimentation and fun!

A Collection of Simple Experiments Using An Automotive Ignition Coil.  Such as Jacobs Ladder, Low Pressure Plasma Globes (Bulbs), and just plain arcs. 

A Collection Of Three Jacobs Ladders all powered by my Ignition Coil.

An Ever Growing Attempt (always acquiring new supplies) at a Series Resonant Transformer.  When finished (soon) it will be capable of creating 2' discharges.
