Van de Graaff Generator
now you want to take it a step further and up the spark current.
A good way to do that is to use a leyden jar and build up a large charge in it and watch the powerful sparks fly.
This Leyden jar is made from a 5 gallon bucket and stores enough electricity to kill you.
I strongly recommend building a smaller one unless you know what your doing.
The leyden jar is a very old design dating back to the late 1700's
Its simply put a high voltage high capacity capacitor.
Built properly and treated like a loaded gun you too can make your own miniature lightning bolts.
Trust me when i tell you that a discharge from this device is loud enough to damage your hearing so wear hearing protection.
I have experimented with high voltage for many years this is one of the more dangerous projects I have completed so please be careful. I accept no responsibility for your injury or death.
Have fun and please be safe,
Next up parts list.
Step 1: Parts and tools needed
5 gallon plastic bucket
Roll of aluminum foil
copper pipe 1/2" diameter or larger
small piece of copper sheet
round door knob
spray glue (i used contact cement)
Drill with bits
Step 2: Ready the Bucket
Next you will want to make a perfectly level line around the bucket about 10" from the bottom.
I stacked some books next to the bucket and held a sharpie on them and turned the bucket around wile marking a perfectly level line.
Step 3: Tape it up...and spray
now spray the out side of the bucket with a few coats of contact cement.
On a smaller leyden jar i would recommend aluminum duct tape, but you have a huge surface area to cover on this one.
let the glue dry...
