Simple Saltwater Capacitator

About: I am 13 and I want to go to West Point and become a sniper.

I am going to tell you how to build a simple salt water capacitator for storing energy or for a Tesla coil.

How to build a Tesla coil
by DevCoder

Step 1: Materials

1. Snapple botle
2. Foil
3. Water
4. Salt
5. Canola oil
6. alligator clip
7. insulated wire

Step 2: Building It

1. use a little iodized salt packet and poor it in the empty Snapple bottle.
2. Put water in it all the  way to the beggining of the threads
3. put in Canola oil to it is almost to the brim.
4. Put cap on  and shake
5. Wrap entire bottle with aluminum foil
6. punch small hole in cap
7. Insert insulated wire into bottle and have an alligator clip at the dry eng
8. charge it with a power source like a battery

Step 3: Using It

Now you can use it to store energy or even make 5 more for a Tesla coil.

    Do you think the lid would rust shut because of the salt water? or does it have a coating?

    oh, and how the wire is set up in there throughout each bottle still confuses me.. do u cut the stung so it is open in the water and then put another end in there from onother wire and continue it to the next jar, and so on and so on?

    is it possible to use like 6 pickle jars, or spaghetti sauce jars for this instead of snapple jars?

    I was just using the picture because I wasn't building a Tesla coil or I would use my own pictures I just wanted to show how they were used I just built the capacitor.

    Can you please use your own images, especially not from another Instructables member. Which you blatantly ripped off from DevCoder, It's just wrong.

    Well it is somewhat the same principle as one but I called it a salt water capacitator because I was focusing more on using it to store energy for a Tesla coil than as a Leyden jar. But thanks!

    Wouldn't this be better labeled as a Leyden Jar? Other than that, great job!
