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
5.Electrical tape

The first thing you do is get the cap and put a big screw in it.

Step 2: Tin Foil Time

Now take 15inches of tin foil and fold it in half :)

Step 3: Almost Done!

Now tightly wrap the foil around the bottle and tape it in place.It is very important that it has almost no air bubbles between the plastic bottle and the foil.....

Step 4: That Wasnt So Hard Was It? :)

Ok ... Now if you want you can tape a wire to the foil and then wrap the whole bottle in electrical tape (thats what I did)

Fill the bottle with water and over saturate it with salt,baking soda
(Right now I'm trying water and vinegar 50/50 mix)

DONE!

These capacitors work great in small Tesla coils and they make a very loud noise

Have fun and be safe
