In this Instructable I will be making one of the easiest high voltage capacitors that I know of.....
WARNING High voltage electricity can cause death and serious injury.I do not recommend that anyone work with high voltage power sources unless they know how to do it safely.
Step 1: Getting the materials
You will need:
1.A long screw
2.Some tin foil
3.A 2L bottle
4.some salt and hot water
The first thing you do is get the cap and put a big screw in it.
