Well, this instructable is for you! It can make create a few kilovolts of static-like sparks, and best of all... You can make it with only two things to make it, a battery and a simple mains transformer!
Before you continue, you should know a little bit of information about transformers, click here to find out.
Step 1: Get the things!!
- 9 volt battery.
- Mains transformer
Unfortunately, I burnt up all of my alarm clock transformers while ago... :( So I will have use a transformer from a VCR.
Step 2: Wire up the transformer
The two leads of the transformer that are connected to the mains power source, is the primary (the high voltage side), and the other two leads are the secondary (the low voltage side).
We are going to connect the transformer in reversed, I mean the primary (the high voltage side) of the transformer becomes "secondary" and the secondary (the low voltage side) becomes "primary".
So we are going to connect the battery on the primary (the low voltage side) of the transformer and we will get some sparks from the secondary (the high voltage side)!
Right, attach the wires to the transformer!
