First some safety issues; this project runs off 240v AC or 120v AC so please be very careful as house hold current can kill instantly, if you touch a live wire your hand will grab the wire and you wont be able to let go. I found this out the hard way. So do not make the same mistake as me. Oh when sparks jump to the earth they generate ozone which can kill if you breath in to much , only small amounts exist in this case. I am not responsible if any property of yours is damaged or you or some one is injured in the process of making this.
To make this the components you will require are:
An ignition coil the old sort.
A light dimmer preferably over 1.5amps or 400w
Wire any sort
A large light globe incandescent for the plasma globe
A container if your making a plasma globe
A cord that can plug in to the power point, please don't take the one of the TV or fridge find an old one that is no longer needed.
Some oil and a jar if you have a low rated dimmer.
A hot glue gun is very handy in making something like this.
